First she needs got be level 10 for mulch 2 because mulch 1 does far too less dmg to kill even Minotaurs.
True, but still, level 10 isn't terribly hard to reach.
Second... if she does it all the time, why don't you just walk behind the creeps and kill the shamblers?
Because I'm sure my time is best spent being hit by a shielded QoT's AA's while I try to kill ~1k hp shamblers that give me no experience instead of capping flags or trying to get my horrible team in gear.
Third... if she does shield the allys and cap flags, he/she must have good micro and if 2 of you suck... well do you want a free win?
Err... what? Good micro? The game doesn't *require* micro. It's as simple as "Shield. Send shamblers. Seven seconds later: Shield. Mulch." It really isn't complicated. And what the fuck are you talking about, do I want a free win? I never said I expected to win anywhere; considering my teammates were horrible and I just barely kept a positive K/D ratio, why would I? I'm just mentioning a strategy, not saying that it's OP or I should have won.
When she was all the time at the crystal and you aren't able to push in a 3on2 its lack of skill and not lack of balance or gamedesign.
No, that's not the issue. It's not that they won. I never even mentioned that I cared about that. Your assumptions that I suck and think I should have gotten to win are making you come off as a jackass. The thing is, it is bad design to let a QoT be able to get all the gold and EXP from creeps while being elsewhere. Even if it is played in a "normal" way, a shielded QoT can farm two lanes at once by being in one and hitting another. It also seems weird considering all other minion related kills get you gold but not experience unless you actually have LoS. Otherwise, Oak's would be sending their spirits flying about, killing creeps for EXP while he sat at a safe-ish distance.
