The level system on here is different than most other game, which is interesting. However, at the beginning of the game you are handed an uber set of weapons(RF gold) that rival level 40 weapons. Equiptable at level 1.
Basically you will learn that these weapons are an easy way to gimp yourself in a sense due to the leveling system when you are leveling trying to figure out the system. We made it to level(RF powerleveling) 20 before learning this. So OK to see what the alternative was, we make a new guy and this time ditch the uber weapons for regular ones to focus more on our PT. However, Leveling is still super easy on here.
It will took about around 6 hours to get to level 20 with the uber weapon on a team with a friend in RF. It took us 8 hours to get to level 20 without a team and regular weapons the next day. It seems like there is an experience boost at least on chaos servers right now. It seems insanely easy to level up.
Why did they bother making people level if they are just going to hand them their levels so fast they can't focus on PT (even if they try) anyway? You can hit level 23 from 20 in 1 hour or less with a regular weapon nothing fancy. Right now we have a Bellato warrior we are concerned about not screwing him up so that when we hit level 30.
