saying the answer is "simple" and then stating an extremely vague solution is far from helpful. While I'm not against backdooring, the deny feature would certainly be a great addition. If not to creeps, at least to the towers with 20hp.

Backdooring is just one of many strategies in the game.

Learn them all, learn how to counter them all.... and then you can call yourself a complete player...

- My games are not too long
- Tanks in my games are tough enough
- Backdooring is not a problem

OP = flawed logic.

Naw.. get out of here with all that.. some heros were made to bd.. u 18 them out and they have no other purpose (yi).. maybe your one of those people quitting when your down 30 kills.. but why? game is about base exploding.....GO... spend a day playing yi.. hes a comeback hero because of his massive building destroying force.. and his bitter hate for Singed..

Yeah, shut up. Backdooring is as much of a strategy as AoE-ultimate based team comps, or wandering gank squad comps.
Backdooring is simply a technique that emphasizes destroying the enemy's base (which is what you're SUPPOSED to be doing) instead of focusing on teamfights first. If you know the enemy tends to do that, its not that hard to let one champion defend while the rest fight and push.

So basically, you want the game to hand you the options to prevent/delay/punish a Backdoor attempt, while ignoring the options they already give you as being "not good enough" simply because you can't get a team to sacrifice one of their 2 ignites, 3 exhausts, 2 ghosts, and 3 flashes on top of buying wards (and placing them intelligently) to pick up any combination of Fortify, Teleport, or Clairvoyance?

Or, in other words, you want the game to stop a Backdoor without any effort on your part.

No thanks.

enough said ^_^

Your team can also do the same thing or OMG counter it? One tele and you could kill them.
