So before I go into my question I want to link my character sheets. The first one is my fighter. It is a Girtablilu that kept the level10 stats from the bestiary as its base stats and is now progressing normally as a level 6 fighter going into level7. The second is my gunslinger with a homebrew weapon(This campaign uses mana arms instead of normal firearms). Both characters are -far- stronger then a regular fighter or gunslinger of their level. This a extremely high powered campaign and we are all decently good at max/mining so its a bit different from normal ones( As a party of 5 we took down 2 Adult Blue Dragons and 1 Young Adult Blue Dragon in a single encounter last night and each receive about 30-45k gold each in total for quest and loot combined). So please keep that in mind when giving advice.

I control and RP both of these characters(there is also a large amount of RPing) and they are a duo. Caitlyn(The Gunslinger) stands on Renraks(The fighters) back and fires away at the enemy while Renraks abuses range to Ready Action and AoO sunder enemy gear/kill them.
Im currently really really liking the fun combo but hit a bit of a wall with my fighter. Ive played tons of spellcaster and a bit of ranged characters but the only melee Ive ever played in Paladin(and lets be honest that class is hard to fail at). As such Im really inexperienced with all the melee classes and cant seem to find a suitable class for my Fighter to Multiclass into. Leveling any more in fighter is a waste because there is nothing left for her to get except for a few +1s to dmg and some situational abilities i will never use.
If anyone can help me on a good class to multiclass out of fighter into that would be really awesome. Ive been looking at barbarian and Inquisitor but I cant seem to find a good archtype that fits the battle style we have been going for(though I may have missing something Im sure).
Any help into this semi-stressful delima would be much appreciated >.<
