The fact that a GL Kenobi gets unresistable stun, an up to 60% damage reflect or 6% Ult charge once per turn, and the two first ones being Faction-specific, makes him a lot more difficult to beat than he already is. It screws up the current counters to the point even they aren't a guaranteed win anymore. I don't think it is anyhow fair that the undisputably strongest PVP Galactic Legend gets these kind of extra boosts while the others are just... eh.
Yeah Rey gets these bonuses too, but from a PVP perspective she is much easier to handle.
I don't think Datacrons should impact GLs themselves, and exclude the bonuses if one is an ally, but if they already want to, at least there should be a bonus for all 6 GLs.
