Without locks people can just abuse blink/teleports/invisible to capture portals which is gay. I think locks are necessary but are a little powerful right now. One of these three solutions should fix the problem.
1) Halve the time it locks the flag to 2:30.
2) Double the cost of the item to 1000
3)Add an unlock item for 1500 gold.
If one takes place, you just need to defend a flag for 2:30 minutes. If people keep suiciding to cap it they are going to lose a lot of money real quick and you're going to get a huge advantage.
If two takes place its going to cost a lot of money to lock all the flags all the time. Therefore adding strategy to which ones you lock. If you spend 3k every five minutes, the other guys is just going to straight up own you.
If three takes place, it won't be as invincible, but still require a lot of strategy of when to use it and which character buys it.
I think the larger the map the longer the lock should last because on larger maps 2:30 wouldn't matter. Yet on the current map I think it would be about right. Taking locks out of the map really just make the game more about chasing than forcing team fights which are more fun than just running around capping all the time.
If we were just going to make it slow the cap it should be more like slow it by 200%. Instead of taking 1 minute to cap the flag it would take a full 3 minutes.
Innociv I love how you make this comment "Just because somethings useful doenst' mean it's too good or needs higher cost. I HATEEEE when devs nerf things because people like them ;[) on the portal there, frost nova, lock flag, scroll of warping out."
So you can apply it to scrolls of teleport but not to flag locks? Just because flag locks are useful doesn't mean it needs to be nerfed. I agree it probably does need some adjustment, but the idea behind it is necessary.

P.S: Portal flags should take a lot longer to cap regardless of lock because they are much more integral.
