Arena - drop Apoth and Umbral, add Helior and Cardinal. Eventually, if you can get Stoneskin gear from Hydra, make a Stoneskin Hydra team. When you get atleast four pieces, start another thread and we can see what works best.
Dungeon - drop Sepulcher, replace with Frozen Banshee, assuming your Draco can wave clear.
I dont believe that I have Helior yet.
Wave clear?
Yeah sorry. I mistook Champfort for Helior. Go with Scyl instead, on that fourth spot.
As for my Draco comment - what I meant was, if Draco can get you through the waves on his own, then you don't need Sepulcher, Frozen Banshee will speed up the boss. But if the waves are what is slowing you down, then you'll want some more damage, in which case someone like Kreela or Fu-Shan should help.
So that you understand arena, I'll explain this: normally players equip themselves with about 200-250 ACCu to easily farm in dungeons, that means that if you have 200-250 REsis, they will lower your armor and therefore your rhazim, which it is based on defense damage, it will do damage as lvl 1 if it has time to hit. And for you to resist those debuffs, I don't know the exact percentage table, but with a minimum of 100 REsis on the enemy, your rhazim could win the arena by itself.

When you say "died on the first round", do you mean from the Scorch ability? Were you not able to stop it from using that by landing enough poisons?
Your speeds are a bit on the low side. What would it take for you to push those numbers up above 200?
Also, in terms of masteries, did you make sure to take Whirlwind of Death? The extra speed from the kills helps greatly.
I can farm Dragon 20 with a full team. It is slow and I cant pull anyone along to level them up. I have to do something to improve.
There's a few things you can do on that front:
