Finished the game on hard dificulty two days ago as a beguiler/debonaire and had so much fun that I decided to replay instantly but this time as a chanter (bc I love bards as much as I love summons) multiclassed with another class that might increase my overall dps. And then the problem began, bc im stuck at the character creation screen unable to decide between Harbinger (street fighter/troubadour) and herald (kind wayfarer/troubadour)... And since I have some concerns that influentiate my decision (or lack there of), i'd really love any help. (firstly, I wanna say that I plan to use this character as a summoner with two blunderbuss (i dont know how to say this thing in plural so I wont even try) and second as a debuffer, with xoti as healer, Eder as tank, maia as dps and ywin/serafen as suport... so lets get it started.) Question 1: Ive seen a lot of people praise heralds as great healers and tanks, but although I really like the idea of being durable, I have concerns if the paladins's auras, passives, FOD and sworn enemy Will be enough to make my character a great heavy hitter? (taking the buffs to summons into consideration) Question 2: Regarding harbingers, I really like the idea of blunderbuss street fighters mixed with chanters, but my concerns lie in their ability to survive at the front-midline, hence my question, is the chanter kit of the harbinger enought to secure its survivability? (ill have xoti as the healer)
