My problems with summoner? I hate the way Egi look, the distance of Bane and, how long a cast time tri-disaster has. Thats about it.

I understand why they put more of the damage on the caster than the pet because of what problems it would cause for game balance. Make them too weak than smn as a whole sucks(case and point ffxi). Make them too strong than the class becomes overpowered. The real problem is theres no happy medium because they will not be taken unless they are OP. Let me try to explain with an example

Lets say they switch places and made the egi deal more damage than the player. W/e it dies it will cause the smn to lose a lot of dps while its down and this will cause ppl to believe it is an under-performing Job for endgame(that was the big problem with pup in ffxi). If they decided to fix this problem with making the pet take a significantly less amount of damage than it would becomes OP because the pet will do all the work while the master is essentially playing support. There are not a lot of mmos that have the pet do more damage than the master or even close and every one i seen that it was the case, the class itself was considered weak and niche.
