Well… you can’t blame a damage class to do what it is supposed to do. And it depends on which kind of mobs are you resting your scenario on. Yes, early stages of Challenge Modes, low levels of Earth Tower and Saalus/Dungeon this can be true, but as CM and ET goes up, I’m pretty sure you can find room for your damages.
And, TBH, for iTOS scenario right now, it should be kind of a bless to not have to cast your PD damage skills and burn your SP all the time with easy to kill mobs. Just find room for your other classes’ skills. As an example, this is what I do with my Pyro3 Kino3 Sage2 - I can either burn my mana down with Sage skills on easy-to-kill mobs, or I can combine Pyro and Kino skills during these moments and save my sanity. I will let you guess wich one I prefer haha
You can’t, but Rank10 is right at the corner, we can expect it to hit iTOS within 2 months or less. You can have Druid2 PD2 if you want, or even Druid1 for cheap support and go all out PD3. Just think on possible combinations, it is not that hard.
Again, you are expecting a support-oriented class to be better in damage than a damage-oriented class. But I could gamble and say that this build right there, soloing CM, would be accepted for velcoffer too.
Note: if you want to party Velcoffer with Meta Rangers, then you have to play those Meta rules. Once you go out of it, you will see that there are rooms for a lot of things. Just think on party composition.
