I really dont mind TK with normal weapons, mortars, or guys jumping on my smines... specially if they say sorry.
But man, one type of TK that makes me rage quit instantly is when you are in a tank, and either a friendly tank or plane kills you... I mean, i have been playing FH2 since 2009 and im more than sure that i have never made such a TK. Few days ago i was on a crusader in superchange, kinda isolated and sniping the axis panzers, and then i hear the beaufighter coming...
I cant tell how many times people shot me in a cromwell.....
One tip that do wonders in infantry TK or vehicle TK... CHECK THE FREAKING MINIMAP
