Dragoon at lvl 38 and forward

So DRG doesn't do the same thing every HT use just due to the durations of moves, at 48 when Dis gets extended to 30s you wont need to use it right after HT every time.
With the 20s dis you will need to use it every HT use, I quickly messed around with 2.5 gcd on my drg and it seems that you can do HT-ID-Dis-PH-TT-VT-FT-TT-VT-FT repeat, you'll get HT in right as it falls off but Dis will be dropped at about HT as well so ID/Dis wont be done under the effect of it and you'll be able to do Ph right as it drops as well which should be just fine for leveling. If you want to just play more how it will end up playing later you can just do HT-ID-Dis-Ph-TT-VT-FT-HT-ID-Dis etc with the only difference being the exact spot you use Ph to make sure you aren't clipping it by more then like 3-4 seconds ideally.
At 50 you'll be able to get 2 combos and Ph in during HT with some clipping with 2.5gcd. For 50 i'd be more like HT-ID-Dis-CT-Ph-TT-VT-FT- HT-TT-VT-FT-Ph-ID-Dis-CT- HT-TT-VT-FT-Ph-TT-VT-FT- HT-ID-Dis-CT-Ph-TT-VT-FT kinda deal
Here is a flow diagram made by the person who did the first guide i linked: http://i.imgur.com/hJFTfLf.png
It's not a true just repeat what you do kind of class rotation but more of doing what needs to be reapplied/FT if nothing needs to be reapplied in the next ~9 seconds.
