i know there are some similar posts out there but i want to be sure! the thing is that i currently have a swordman C2 barb C2 corsair C1 and i was planning to go corsair 2 and doppler in rank 7… i know i miss the peltasta and that later on it will be important for us swordies to have the swashbuckling skill but i cant turn back time 
can i make this up? maybe sacrificing 1 rank of corsair ? or my build is viable the way it was planed? i need some advice guys i dont want to play a char and be useless later on … TY in advance
You won’t be useless. Gung Ho, Pain Barrier, and heck even the knockback from level 3 Bash is good. You’re just missing a bit of evasion (can be made up with armor and stats) and have to press a couple more buttons on occasion for mobbing things. I’m Swordie2>Barb2>Corsair and eventually Fencer2. I can solo plenty so far, do not underestimate not getting knockedback by a few more seconds. I wouldn’t give up Corsair 2 for Pelt any day.
They really do need to make a class reset item at some point though. So many regrets on this forum.
Looking at that build I can say that you wont be useless. It really depends if you’re planning for a tank role or not but looking at that path you’re on the dps side which is I think i still pretty good. Barb and corsair has good buffs/dmg. Even the swordsman class with concentrate and gungho. Combine it with deeds and cyclone for doppel and you’ll pretty much have high dmg output.
