It might be enough for them but everyone should know that their opinion is worth nothing if they didn't even play an iota of the game experience vanilla offers. Obviously the full game experience someone might identify as such is very subjective, but playing until lvl 5 is nothing. As I said, if someone thinks that RPGs for them or the whole of world of warcraft isn't their cup of tea, then I understand, because questing and killing mobs is a huge part of WoW. In the situation of OP, this wasn't the case and blaming merely classic for being a bad game is dishonest imo.
Also if you assume I am some kind of "vanilla hardcore fan" or part of the "pro classic" crowd, then you would be wrong. I think retail has many advantages compared to classic and vice versa.
