I hate the fact in vainglory you've got to buy stuff every match to level up whereas in coc you can level a class/character and it will keep its level and perks. The only problem is I find both games very tedious but that might be because I'm a massive fan of the legends games due to having so many things to do.

Saying that I've only really played against bots in coc so maybe more games agasint other alpha players might make it much more interesting. It's alpha so it's only early days in development so I'm am very interested to what else is implemented in champs.
