While we may have the same 3 Titan, Warlock, & Hunter classes, not all of the abilities stay the same. We’ve been introduced to the Dawnblade, Sentinel, & Arcstrider.
The Dawnblade (Warlock) makes you go all Jean Grey Phoenix but you’re reigning down fire from swiping your blade.
The Sentinel (Titan) has you representing your favorite stars and stripes Marvel hero Captain America. Shroud yourself from bullets, bash enemies heads in and most importantly, throw it at them.
The Arcstrider (Hunter) summons a glowing staff which lets you flip and strike your way through enemies with ferocity.
