Death timers still far too long

I've just finished watching the EU LCS and it summed up what I've found in games I've played. The death timers are still far too long at average game length. If you die at 30+ minutes you are looking at a 40+ second wait to respawn and that's ludicrous. If you ever get past 40 minutes you may as well go afk and do something productive if you die because that timer is not getting any lower. If you lose a big team fight you used to lose a tower, maybe two and an inhib at best but now you can be wiped and the game can be over before you respawn.

The last patch supposedly lowered the death timers but it sure doesn't feel like they are any different to me right now so will they be looked at and lowered again? If not then the already rushed game feels like the first team to win a team fight wins the game.
