problem - no consequences to team killers themselves. I'd argue the 1500 limit is way too high and no one rly thinks they have to worry about doing 'team damage' and thats why they do it, the classic 'fuck the teammates I want that frag' mentality. Consequently they ruin the experience to every one else and get punished in no way whatsoever.
solution (proposal) - reduce the TK kick limit. Some limit is already there, so apparently someone had good intentions in reducing team damage but also keep it high enough to protect 'something' or 'someone'. Who though? Newcomers/amateurs dont do a lot of team damage. Objective based gameplay doesnt require high TD. Anyway, 500 sounds like a golden limit, but how about we start with 650 and test it out? Prediction: it wont end up in people getting kicked more often, but rather toxic players adjusting their toxic gameplay to new limits which reduce toxicity

Modern games dont even have team damage enabled and they are way less spammy than ET. Not saying that TD should be disabled in ET, just implying that conversation about reducing TD is not unorthodox at these times.
Ppl are pissed off about this, aint just me, I see it regularly.
