Running him at 4* in arena with a full tenacity set of mods:
- Speed arrow
- Protection in all the other slots
- 199 speed, 68k HP/Prot
- Potency 52%, but am missing a piece or two
- Gear X, missing 3 pieces
He taunts round 1 if debuffed early (e.g. Sun Fac counter, B2 etc) and his cool down is reduced on the taunt if he is debuffed, so its good to get a few buffs on him. I run Rex as a support (not lead) as with critical hit immunity, Rex doesn't get fed. But its nice when someone runs B2 to clear the Shore taunt as Rex says thank you very much on his opener with squad discipline. If the team around him keep buffing him as people clear the buffs it just keeps on taunting, team healing and giving immunity. Potency I'm not too bothered, north of 50% is OK about as its not that often that it gets to use its primary as it taunts more than fires.
