i think summoners should get a JA that allows a BP to be used without having to wait 1 minute to be used again, so can do 2 BP rages close together once every 10 minutes maybe and this ability could also be used to allow the avatars to chain BPs like a WS and make more use of lower lvl BP, example Double Slap > Rush = some skillchain.

also i think all avatars should gain En-spells and Spikes, Ramuh is the only one that has the both, would make more sense as like gods of their respected element to have each avatar with these BP wards, would make smns more party friendly and they could find out enemies weakness and use the correct buffs for the party to give them that edge.
