I find Axton a really cool character to play as. I’ve taken him to 72 3 times & op8 once. The turrets rock. With mag lock & the longbow skill & creating a distraction.
On another note, I’m certainly going to change my approach with BL3. I played Maya to begin with and while she remains far & away my fave I didn’t even try another character for months. When BL3 drops I’ll be tying out all the new VHs. If it follows the same pattern, where the level cap will be 50 for a while, there will be plenty of time to experiment. With a 50 cap that also means 1 capstone skill & about half another tree, making for more specialised builds.
I had fun with Kreig although I hardly used the action skill. Zero is awesome, but I find him challenging in that I have to really ‘play’ the game & concentrate rather than relying on BAR or gear. Good luck!
