Rets are a utility class with great burst potential. Dks are designed to be somewhat like warriors where damage is superior in pvp situations and are able to stick to their targets better than a ret can. So if you enjoy just doing damage then dk/warrior is probably going to be more fun for you.
In 2s for example:
If you run ret/healer then you should win most games against equally geared/skilled double dps teams. But be prepared for longer games against dps/healer teams.
The other thing is that we are talking about 2s it seems. 2s is just not balanced and it won't ever be. Ret in 2s is much more fun/playable if you run double dps. Plus the games are shorter.
Ret is a fun spec for me because I love the utility. I like being able to off heal and freedom etc. I understand what rets aren't which I think many players don't. They want the utility and the cc and the sustained damage but that just isn't going to happen.
Looking you up, you are behind on gear which is going to cause you to run into problems against equally skilled players who are full s13. Also it looks like you're missing several enchants which some might not think is that big of a deal but when under geared everything matters.
If you normally run with a healer, make sure they are chipping in with damage especially against other dps/healer teams when you have the off target cc'd. Against double dps teams you should be able to wear them down so focus on making sure you los their burst, use your sacs to get your healer out of cc etc. If you play double dps then just make sure you are not overlapping cc, and don't be afraid to turtle when you can to heal up. A lot of players run in pop cds don't get a kill and are at 50% or lower and think they can just keep bashing away. If you ever watch a streamer such as Vanguards (especially 5.2) you'd notice he los'd a ton and flash of light healed himself even with out 3 stacks of selfless healer. Without knowing exactly where you are struggling I hope my humble opinion helps.
Im no glad, but ive been over 2.2 before and over 2100 on this toon this season.
Yeah I know part of it is a gear issue, and I factored that in when I made this post. I think most of my issues with Ret come from being dropped just stupidly fast whenever anything switches on me, anything at all it doesn't matter what it is. I try to los and heal myself, I try to kite but I usually get trained right into the ground.
I also have a terrible time staying on target, particularly on healers. Say I've got a healer into a position where I can kill him, I'll pop cds and obviously get cced. But the real problem is whenever that fear/stun/blind ends I can never get back on him and I usually can't switch onto the dps even if I try to.
The other thing is I don't understand how to keep pressure on the enemy team because usually I'm the one being trained. In which case I have to use resources that could be used for damage to heal myself, even though most dps could burn through my self healing anyway. Where as if I'm on my dk, I can still do decent damage with conversion up.
I'm not sure if this is a L2P issue, or if I'm simply playing the wrong class.
