Dragonite with Steel Wing / Outrage

I found a Dratini not too long ago at level 27 (cp651, 91.1%) and evolved it to my first Dragonite about a week ago. It got the same moveset. I've powered it up since and don't regret it. I was hoping for Dragon Tail, but I'm satisfied with it regardless. If I were you I'd do it

Something doesn't look right. a level 30 dragonite with ~80% IV will have approximately CP 3000 or above.

My IV 64 at lvl 30 has 2941 CP.

Anyway, if it truly is at level 30, I wouldn't power it up further. You can already use it as it is.

Recently evolved my 100% Dratini and got SW/Rage also. Initial reaction was disappointment, since I was conditioned already to think of SW as the slow defensive move pre-update. But after looking at the new numbers and actually testing him out in a gym, I think I got lucky! Dragon Tail is slower and hits harder so that's the new best defensive quick move. SW is faster now at 0.80s so you can strike twice before having to dodge. Outrage dishes out a ton of damage; two bars of 110 each! The new defender/attacker lists aren't out yet, but I'm pretty sure Outrage will be the top move on both offense/defense. And DT for defense, SW for offense. So basically having SW/Rage means you have an "A" attacker, and a "B" defender. I'll take that combo any day. The key ingredient post-update is having Outrage no matter what.

I wouldn't complain with SW/OR - Power that dragon up and use for either ATT or DEF. It's a top mon any day of the week!
