since you barely have anything to weave in between GCD's as is.
How to spot a non-Dragoon player 101.

It's top 2 busiest classes in the game.

Anyway, I don't begrudge the pet idea except not for normal gameplay. I think they should just expand the companion system and some jobs get unique companions. Dragoon can get one, and it can stick outside the natural party balance and instanced zones. I think it'd be interesting and fun there.

Fantasies aside, this worries me. I like how busy my class is. And I'm worried they'll hurt the flavor.

That said, my common complaint is the lack of defensive or unique feeling DRG has. Most classes have some oGCD so Jumps don't feel special. It's a damage weave button like anyone elses (basically). So I kind of would like a non-damaging jump that just sends us in the air to avoid damage. Non-damaging because if it did damage we'd be forced to waste it to increase dps. Dragonfire to go back to a ground target (especially if we can set it to GT if we have no target selected and to fire automatically if we do).

Keep Life Surge.
They could add Lancet, a couple DRGs in the series have it.
If they wanna idiot-proof, make Elusive not take us off ledges or in to death walls.
They can turn Dragon Sight in to 60 seconds, keep the ally buff and add Lance Charge's buff in to the personal buff to reduce button bloat and maintain same personal dps numbers. Raidwide technically goes up. Could always adjust if needed.

I'm not sure about positionals. A lot of the time it really is a hassle and can be a pain, but I'm also remiss to just dumb down my favorite job. I laugh when tanks tell me "True North" with no elaboration like I don't have enough weaving as it is. If I have to TN every time they don't want to adjust the boss properly I will lose positions to 0 TN charges, truthfully, because some bosses (like P3S) demand you use them when their positionals are not available.
