How to end all that complaining about assassins at once:

Stronger towers - that's the simplest solution.

I'm not pissed that Fizz can kill me if I walk out and he outplays me. No, that's ok. What I have a problem with is that when I'm behind in lane and I try to hug my tower and he dives he can fuck up so badly, get hit by hard cc and still get away with it because towers might as well be stationary caster minions with almost no strategic value.

What should be done is to increase the ramping up damage of towers dramatically. The first shot still deals normal damage. but the second and especially the thrid and fourth ones deal significantly more. For this there are three ways.

1.) Towers deal true damage 2.) Towers just deal more normal damage 3.) Towers gain +20 flat armor penetration with every consecutive shot.

I really like the third option here as tanks can still, well, TANK turrets, but squishies who have no resistances will get torn to shreds if they dive brainlessly.
