Title says it all. Anyone can tank tower for days if they build a small amount of HP and minimal armour. Was playing vs fizz with protobelt and seaker's armsguard, he missed all his stuff except for Q and AAs took about 6 tower shots which barely did 25% of his HP and he just auto attacked me to death. (from about 40% hp to 0).
Also they just die way too fast. All it takes is one gank top lane with a decent sized wave pushing in and that's first tower taken, mid/late game it takes one ace to push an entire wave to the inhib.
I seriously think towers need to be looked at and buffed. Just my opinion.
