Why does Cocoon only last 15 seconds? It lasts for 3 minutes when normal crawlers use it, or even 1 minute when a BLU casts it, but it's the only useful move crawlers have, and the short duration has taken even that away.

If a wild crawler spends 100 tp to get a 3 minute cocoon, so should we. A shorter duration for BLU's makes sense as all they need is a handful of mp, but at 100 tp, what use is a 15 second buff you could never hope to use more than 1/5 of the time?
