An omi setting “new toons” to higher base stats is a good idea, but problem is it doesn’t help at all if the feat the new toons are used for is something like “win 40 battles with a full team of Gungans”.
Also while it would help, you would still need to have a strong setup with a good tank and Wat or VV etc for it to work as just slightly higher stats compared to g11 isn’t going to help enough in many cases.
This could leave very little room for the conquest omi toon to slot in, so again I would be quite hesitant to stick it on.
But your suggestion is certainly one of the more appealing ones and would possibly help some players.
