Should I get Azir or Velkoz?

Vel'koz is in a much better state right now than Azir, and doesn't require big plays to win games. He's also a little bit easier mechanically and does more damage earlier. Plus I'm a Vel'koz main.

I find Azir more fun and more versatile

Neither

You need to make the choice. Azir is probably the most difficult champs in the game but is really rewarding, he can poke hard and make insane plays, while velkoz is a very safe poke champ who can chunk HP.

azir is trash don't bother.

Easiest way to answer this:

Do you want to have to put 100+ games into a champion in order to grasp the fundamentals of them? (Azir)

Or do you want to be able to grasp them faster, and have more versatility in how you play? (Vel'koz).

Personal Opinion: I say Vel'Koz. He's a great midlaner and an amazing support. He's pretty easy to grasp after a few games, all you need to practice on is his Q timing and positioning. Outside of that he's a very simply artillery mage who functions well as a support.

Azir is great and I love him as a character, but he requires a lot of patience and learning in order to actually be good with him. Sure you can take him bot if you feel like it, but it's best to stay mid since he does shut down a handful of popular picks due to his crazy range and damage. He's a great champion to push yourself, but he has a huge learning curve and can take a lot of time before you get decent with him. It's kind of why in the right hands he becomes an utter monster in the game and can't be stopped, but in the wrong hands he's just a worthless sand chicken with free turrets lol.

Just my opinion though. You should always play whoever you want to play c: But regarding those two I really recommend Vel'koz.

Azir is great, he's a pretty safe midlaner and has mobility which Vel'koz lacks. They both shred through tanks, but vel'koz is way easier than him. If you hit anyone with your Vel'koz Q or E, follow up with the rest of your abilities + Ult and they will pretty much die. Play Vel'koz if you want an easier champ that you can get used to right away and have fun killing tanks in 3 seconds, or play Azir if you want a challenge that requires great positioning and kiting ability. He also takes turrets really fast, so there's that. They're both strong teamfighters, and can both 1v1 really well. I'd go with Azir because of his passive and self peel, since his W and Q alone do an insane amount of DPS lategame. It's just that vel'koz has a way better early/mid game and I prefer to play safe and not go for kills that much during then.

Brand. He's more fun

I suggest vel'koz, all his abilities are skill shots and although he's considered easy he's not stupid easy or stupid hard but he's inbetween and very strong, squishy and immobile but if played right you can turn it around and kill at least the jg in a gank

Azir used to be good, he was gutted for a while now and he sits at a 43% winrate, he's super hard but not as rewarding as he was anymore, Azir will be getting a rework soon though so he might make a comeback and be strong again but for now I'd stick with vel'koz

Also, I find it kinda funny that you're choosing between the lowest win rate mid laner (Azir) and the highest win rate mid laner (vel'koz)

Azir is very good if ur a god but vel is better

The one that's not shit-tier garbage. AKA, Vel'Koz.

velkoz. way easier to play. less flame from teammates. does true damage. simple build. higher base stats. doesnt require combos to deal damage.

play Vel'Koz. i main vel and he is stupidly overpowered but no one plays him. if you do play him here's a tip, once you have learned how to play him, play him top lane, he melts tanks. also, if you feel you need a little support in mid bring heal instead of ignite, heal is useful for getting out of sticky situations early game

certainly not azir

velkoz is pretty good as mid and as a support, azir is just in a sad spot

isn't Vel'koz free this week? http://na.leagueoflegends.com/en/news/champions-skins/free-rotation/extra-supports-free-champion-rotation

try him out first, if you don't like him, get azir, no guarantee Azir will be better for you though
