There is no denying that there are less support player to DPS player. But , if you are playing a DPS you are also getting cherry pick among a sea of DPS, I personally lead multi Valtan run. I definitely cherry pick DPS, to give us the best chance. Duplicated class in the same party is generally bad due to you losing on the class specific buff… ie DB head/back attack GS crit rate etc etc. Just an observation, had successful pull using GL as an off support and one normal support, so having two support is nice but not required.
