I cannot deny your logic here and I surely trust your experience. However, I feel you are exaggerating somewhat. Even assuming UB is doing mana solo non-stop unchecked and I share a lane with someone, it will be more like 10-13/14. Your main point is clear and totally valid, though. Guess I have to get some games that are, basically, equally skilled UB duels to draw my conclusions. No luck yet, it's always asymmetrical: either my UB is much stronger, or vice versa.

I'd argue 6 is generally the best the time to pick up silence.  Just early enough to keep a sigil from going off and result in a kill on a decent team.  Right around lv 6 (FOR SEDNA), folks are either getting ready to pick up sigils or may already have.  Obviously, silence is a huge waste of mana if its misused or if you are a support sedna that is soloing.   I'd just say it makes a bit more sense to have an ability that can shut down the enemy team if needed earlier instead up being able to do an extra 200-300 damage on a pounce. 

May or may not be the case, but I can also say that there would have been no chance for a kill with an extra 200 damage at that point.  The odds for a kill or a save are > if silence is available in my experience.  I'd always rather have that ability sooner than later.  Its somewhat moot in the land of hypotheticals.  We're really talking about picking 1 skill point sooner than later.  And I'd say I'd rather have silence in case its needed.  You'd say who needs it until later.  Both are valid points in the scenario where I catch someone with silence or you catch someone with an extra 200 dmg and manage to snag a kill as a result.  It also stands to reason that I must have found getting silence at level 6 is a better decision, whether or not you agree with that in the few replays you saw clearly showing my 300+ games using sedna   Unless of course a couple of tourney games is the sum total of my experience with sedna, eh. 

I think the times that I didn't get silence earlier like 6-7-8 I wish I had gotten it because I missed a few kills. I do really find it effective once your team mates are hitting their level 7 nukes and for sure you want it by the time they are at their level 10 nukes. I can see where you are going with it. You want your full pounce by 10 and at least heal 3 in and your HW2 or counter heal. I would rather put off the counter heal or eliminate the IG to get silence in earlier.  I struggled with Hedgie's thoughts on IG but I found it really is just a safety net and I didn't really need it once I got better with her. That 10 hps and speed is awesome but its a selfish skill.  I think I even started putting off the IG untill like 12. I'm finding the same thing with KoM on Occ. It's good to have but that point could be used better somewhere else if I just play a little smarter.

I've even toyed with this, putting off HW 2 a little bit. With your HW1, higher level priests and Heal 3. I found HW2 really isn't neccesary if your goal is more damge.  

I'm actually not exaggerating at all. The last game I played when the UBs hit level 15 I was halfway to level 9. 

I have played a queen both tank and support wise, and both times I would never noy get mulch at level , to me mulch is that skill that you may not need just at that moment, but it is always nice to have. (Cow and Rawrrr aren't the only ones who get away with it, I place mulch on a higher value than ground spikes, but thats just because to me survival is a higher goal than getting that kill. Yes getting that kill is nice, but it was pointless if you or a teammate had to be sacrificed in the process. Any advantage it might have got you has just now been neutralized.
