How would this game be without life steal items?


So i heard you like mages and tanks
People would go back to base much more often.
There would be less action because people were always waking back to lane.
D:
Problem with removing life steal is that healing/regen would become OP.
Can't have that, poke would become relevant again.
one or more of the following things will happen then:
damage would be lowered across the board due to the lower sustain
some form of sustain will be introduced and/or increased in most AD champions due to them not having access to lifesteal anymore
tank stats would be lowered across the board due to you not being able to survive prolonged fights without it making tanks stupidly strong
competely without lifesteal? not a good idea.
but they could put a global 30% cap on it for lifesteal from items/runes/masteries imo. or just give some lifesteal items the same name passive to make them at least somewhat less stackable.
its a bit concerning how much lifesteal people can stack.
warlord and bloodthirster alone is actually too crazy imo.
