I just not play on servers where I not like the rules ...
I always felt, in any game, that anything what is possible by regular game mechanics shall not be forbidden by serverrules ...
as long as it is no bug or glich
So I avoid those servers
AND btw ...
C4 counting towards the minelimit does help ...
planting 10 c4 on a unit would take away 10 mines from your vulnerable spots
that means, there is actually a mechanic to make "flaming" not only an advantage
and it is possible for both teams aswell, not a one sided thing ...
I can not see any reason why someone should forbid this, except for cry babies
