Dragoons need to be buffed...

[Lemon8or]

you can have the debuff from d kick while not beein not entirely on the flank of your target, but that wont really work for HT unless I'm doin it wrong ^^

While it's true that monks have an easier time with buff/debuff application, they suffer a lot more if they're on the wrong sides. Like I mentioned above, Dragon Kick 100 vs 150 potency is a lot (a difference in the neighborhood of 300 vs 450 damage per hit non-crit unbuffed). If you hit from the wrong side with a crit buffed True Strike, it's the difference between a 700 hit and a 1k hit.
You just have to be on flank side when you hit HT button. That's when it counts your positions. I haven't played turn 7 on dragoon since my monk is way more geared but I have plenty of practice with boss turning with Titan EX. It's kinda the same thing though the window is bigger comparing Landslide cast to 2 Circles of Flames cast.
But if you want to compare passable dragoons who can't even buff up properly on Scourges, maybe you should've compared them to passable monks who can't hit from the right sides.

I just want DRGs to have something like Monks have Mantra and INT debuff, so that they would be generally more appealing.

If it's not appealing, why were there so many DRGs when the game came out? There are just plenty of bad DRGs which give DRG a bad name. Mantra? You have that too.

increase Heavy Thrust damage bonus to 30% (THE EASIEST) or decrease all JUMP abilities cooldown by 50% ( might controvercial due to pvp ) is what we need to be on par with MNKs

You want either a buff that is better than GL3 but take 1 GCD vs 9 GCD to activate or 50% CD reduction on your abilities to burst? Are you insane?

Sure dropping from the sky is cool and all, but Monks having higher DPS (unless the boss is an absolute hell for them), and being unable to support your group make DRGs seem inferior.

Like I said before, monks only have higher DPS if and only if they can keep GL3 the whole fight so I don't get why you think DRG with shorter windup should do even more damage.
