You overstate the importance of Trials. It's literally the only PvP mode in which Sunsingers are actually useful. Only mode in which it's a better choice for the neutral game to run a high impact sniper (on a theoretical basis, a high RoF/low impact sniper rifle is better, when revive sniping stops to be an issue). Only mode that is round based without respawns, etc etc. The tactical differences between that and objective based 6vs6 modes (what most people Play) , are too big to balance in favour of the 10% who play trials, or to overvalue the data trials provides.
