Yeah... There are various players and some do talk, some not (until they see you being bad)... I myself not always talk (and sorry for that), but not always I can... Sometimes doing other things while playing (thus not paying so much attention myself), or just simply being sleepy... But if I am fully ready for a game, I try to tell teammates as much as possible (help need depends on demigod, but when needed, I try to ping to allies, because is faster + can try to survive alone).

As for Citadel upgrades... I suggest you asking that before everything "Who will buy Currency 1 / fs 1?". Usual silence leads to the question giver , so tell them at least "I'll get currency 1", etc... Because this way, you can prepare gold for that and could know that you'll buy it (however sometimes people manage to buy before you, even after that...). + Some upgrades sometimes are not good (like troops), so better to ask for other people opinion (against full da team troops are good, while against full tb isn't...).

Some sort of lesson I learned. If you play with others, ALWAYS have tp. The earlier, the better. They not always have, so are in need of help quite often. And tp'ing or faking tp (depends on circumstances), can save him and even get you a kill. Also, when you are not in encounter with any demigod (meaning that probably someone on your team has 2v1), you should keep an eye on him. Maybe he needs help (by the way, do you use mod, which shows allies hp and mp? - helps a lot in such case). However low hp also not always shows that ally needs help.  Regulus with 2 hp and in fog can be dangerous and doesn't need any help.

Team erebus or enemy erebus potion thing... yeah... People must tell allies... Even mines if in dangerous places. (I like to see, when someone sees my mines and avoids them, while their ally comes to help him and jumps on all mines also damaging the previous demigod)

As about the portal thing... You should realise yourself when it's obvious that ally can't hold (if not obvious he needs to write). For example reg vs full hp oak/beast, barely could stand a chance unless he locks it before he captures. Also, this portal should be pinged at least for the attention.

And sorry those people whom I talked bad with in game chat... There are things, which I understand as a common sense (if reg is in team, he buys currency... unless he is totally bad...). Being able to stand alone in line without dying in 1v1 (if not our flag), etc. However even not being able to do that isn't so bad (unless you scream at allies for your own mistakes) If you at least talk, it's good. If not... then what can i say... try to do your best, and watch over allies when they are in combat and you are not.

heh – getting fs1 and telling the team you picked it up in chat is not really bragging imo.  That’s a little silly.  While I can notice that fs1 has been bought, I’m never going to complain that someone indicated they picked it up in chat.  I’m not constantly watching my teams towers unless one of them is getting wailed on and I’m defending – so I might not know that its been bought.  Anyway, I think it’s a good team move to announce when you buy (though a cool feature would have been an automatic announce for your team based on what is bought)

With currency, you can also tell just as easily if its been purchased or not by watching the rate that your gold trickles in, but I’d still rather see a quick note from someone indicating that they picked it up.  Another nice team move.  The best teammates typically let you know in advance that they will be picking up currency so you can plan your build knowing that you don’t have to pick it up (not just talking about a reg always getting cur1, talking about any teammate ready to buy when its war rank 2 and giving the team the heads up).

Good commentary re: mid game.

Re: late game, its gets a little dicey.  Experienced players should be very aware of what’s going on at portals without anyone telling them what to do.  I know what you mean though, a simple bit of communication is very important to make sure you don’t lose the portals.  I might keep an eye on the portals, but I might not be enough by myself to save it, so I need to request help and I do.  If I see any conflict going on at a portal, I’m doing my best to pay attention to what’s going on there – and at the very least I have flashed some fake ports and am ready to come in if needed or there is a kill op.    

Overall, I really agree – if you aren’t super freaking good (eg porting in on your own to get ganks, always mindful of the map and portals), then you should be communicating and people listening to each other.  But if you are super freaking good, you probably already communicate pretty well.

well, you do have to co-ordinate who ports to the portal against bitchy speed stackers. Fuck them. 

Yes , but this is a game not a full time job. You cannot expect people to be flawless at it, and a couple of well timed chat lines make it a lot easier for team mates to work a lot better together. 

I specifically talking about the 'the turn' or whatever you call it. That point in the game where things go from ticking over to bat-shit really quickly, the transition between mid and late game. If your playing in a mid game (I don't play in pro games) and you die, if you could not be bothered to mention anything at all in chat, but then find plenty of time for pumping out abuse, I'm not really sympathetic.  

A few lines of text during a game at the right point can really make a huge difference.
