I would like a level raise... I can definitely max pirates quickly and it would be nice to have something extra to do, but if they raise weapons levels it makes me wonder about svs.
If they add 5 levels onto sailing, I can assume the next thing that a driver might max is broadsides (war sloops), full sail if not already, maybe a little more on open fire, or tacking. If everyone were like this, it would be like a team of supers against each other.. that wouldn't be fun.
If they add 5 levels onto cannon, I can assume that war frigates max explosive/firebrand, or light sloops max round shot/explosive. Now we have fast, small, maxed broadsides lights MOVING on the field too. -_-
