Using Blazing Sol with 2/3 charges isn't useless, it still locks your Solcharges until the end of the turn; which lets you double up on 2-3 cost Solcharge skills.

I don't think I like either of these options. If you increase the duration, you're giving already really powerful buffs another turn (4 turns of 10% ele pierce, 15% mag dr/phys dr or 2 stacks of Combination Fighter); if you make it activate once you start using it, Wall gains more value if you go first.

If it had to be one, I'd go with B).

it would only be 3 turns of of duration really with 1+1 per 2 charges

currently spending blazing sol with 1-3 charges immediately ends the status on the next turn, without ever benefiting from the buff bonus.

with a extra duration 1-3 charges becomes a 2 round buff, ticks down to 1 on next turn, falls off turn after, and you only get 1 turn with the buff bonus.

at 6 charges you'd only benefit from 3 rounds with the buff bonus.
