Dunno about the rest of the brethren, but I'd happily trade -5% Chromatic-based DD/DoT damage for an extra 115hp and 85mp. Not to mention the increase in AC, stats, saves, and all the extra mods on these.
(Comparing these with Keikolin`s Mindhaze Sleeves from TSS.)
Edit: Ah, I see they upgraded the Focus to match the TSS Tier 2 Raid arms. No downside to these at all, now.
