We used to have flash cross class to fill that role. Its gone. It just takes some getting used to, but it really isnt a problem one you get the hang of it. Find mob in the center>Spam GCD>Profit. Which is basically the same deal with AD. Target mob in the middle>Spam for more damage than a pld could ever dream. Just add a bonus of steel cyclone/Decimate.

If multiple adds pop (say doom train) I just use 1 cyclone in the middle to gather them, then take a few steps to the side while gcd ticks down, then OP spam for days. In dungeons, Approach pack>target middle mob>charge through the middle of the pack and they gather up in a group right behind you as you keep running. You now have a clump gathering behind you and the middle targeted. Hit OP just as you pass through them. Repeat until you have everything. If you missed one, target it as you run and tomahawk (or voke>Toma if necessary) it between packs. Pop CDs, get up eye, OP+Unchained or inner release SS/Decimate. GGEZ dungeon.
