IS warriors have been forged in a constant state of war. The clanners were duelists focused on one opponent at a time, deadly one on one but having weaknesses compared to mechwarriors in the vicious conflicts of the IS. Clanners are focused on achieving their goals with the least expenditure of material or life. They do not use trickery or mass attacks focused on one foe. Clanners will retreat if possible when overpowered rather than to fight to the death as might IS warriors.
You are confusing organized TT games with a video game environment. MWO is, when you get down to it, no different than any other RTS in that you have no way to force players to act a certain way or block them from fighting as they choose (which also means players killing their own team for fun, which seems will be quite common with the friendly fire being in MWO). The players in MWO are not dedicated gamers sitting across a table, trying to make an interesting scenerio....they are video game players fighting in a scenerio provided for them who only care about getting kills and trash-talk. They will ignore anything that gets in the way of those two goals (three goals counting doing anything they can to have fun).
Thus, if Clantech is ever put in player's hands, you can only count on players using it in the ways that will ensure they win, and get the most personal number of kills/victories. If that means concentration of fire, breaking a duel agreements, or ensuring members of the other team are placed in bugged locations that they cannot move or shoot in, then they will do so with gleeful abandon, and post YouTube videos of how they dominated the other side.
