I have around 1050 RP left after buying Thresh, Lulu, Vayne, and a couple of chests to get a legacy Morgana skin. But now Imdont know what to do. I kind of want the dragon trainer lulu skin when it goes on sale, but should I buy a champion, like Braum or Zyra? Or maybe Leona? I'm confused on what to do. Does trainer lulu even HAVE parietal changes? Do you have any advice BEYOND whatever you feel like? Thank you.
Ew... dont buy a champ with Rp... pls... it hurts my soul when people do.
What crazfight said... don't spend rp on champs. UNLESS it's the new champ bundled with their skin. :3 I'd wait for DT lulu to go on sale if you want it badly enough.
cough cought refund the champs
NEVER BUY CHAMPS WITH RP
I have never bought a skin just waiting for SSW 
Skins.
You will get all of the champions through IP eventually (and you won't ever really play most of them).
Emojay,
One thing I will say about the people saying "never buy champs with rp" is.. it's totally up to you. If you want to spend money on a form of entertainment that you enjoy (this game) then go for it. Everyone has things they spend money and that others wouldn't.
Yes, you can get champions from ip if you play... a lot. I've played since season 1 and still don't own all champions (a few by choice) because runes and rune pages have been a sink of ip throughout the years (although now better). So it's definitely understandable to bypass playing a ton of games for new champions. You get instant gratification and you support a game you enjoy.
I would suggest holding out for a skin your really want to go on sale.
