... anyone know how much damage the BFT proc actually adds to the shrooms? I vaguely remember it being something like either a percent and a half or half a percent (depending on how BFT reacts to the DoT aspect) of max HP per duration tick, plus another two or so seconds (so ~3% or ~1.5%) after the shroom wears off. Six seconds total, I think, maybe seven... which comes out to <10% health. (Note: Mundo's cleavers hit for better than twice that, at 5/5, and higher at 1/5.) Which... yeah, it makes a difference, but I'm not sure if it's a particularly massive one. The shroom's ticks resetting the BFT proc
does slightly more than double duration of a single proc... which is halved in damage due to it being proc'd off a DoT, bringing the BFT proc's damage back up to... what you get off of Teemo's Q
A little more, maybe.
AP Teemo shrooms just flat out
hurt is the big thing, imo, and they're much nastier on a small, constrained map than they are on something like SR. Plus Teemo's just a pretty decent hero, all around, and particularly so on TT.
What I'd call more likely than BFT being terribly out of line is that everyone's seeing an AP item that synergizes well with Teemo and playing the guy a lot more, and so his natural capability on a small, wardless, map is coming out in full force. People seem to forget that Teemo's always been a bit of a menace
At least since I've started playing League, anyway.
