the first 10 lvls you'll get in one day, and then you'll be in warzones owning it up UT style. seriously it's that fast. you'll have a blast, and the outdoor elite mobs are reminiscent of wow's early days. you have a lot of content to get through and you'll have fun. the warcrack will fade adn you'll be happy and sad. happy because you're having fun and sad because you'll look back and say "how the fuck did i play that crap for so long".
Warzones at low level is totally unbalanced and makes Warzones stupid.
I'm in the Beta, I leveled to 15 and went into a Warzone and I could barely get a high level down due to them having more spells.. You may do the same Damage as a high level and have the same HP as a high level but it's totally unbalanced.
