Thanks to the expanded quest line, and anyone in a decent Clan can level to 150 without much problem following the quests and just getting help on the hard ones. After that though, it's pretty much up to elixirs. The problem here is that the goal is to kill as many things as you can in as short a time span as possible. Droids can do high DPS, but they don't do high DPS incredibly quickly especially when compared to other classes. Also, as mentioned before, you'll get interrupted. Druids have the most difficulty with interruption from any glass. it's because most of their damage often comes from their skills or most of their defense often comes from their skills, or both. While Mages have basically all of their damaged coming from their spells as well, mages have a skill called energy Shield which stops the opponent from interrupting you while it's up. the druid skill sanctuary can do the same thing but it's not nearly as strong as energy shield and so is seldom the best way to invest your skill points. Group leveling, well it is more efficient, is actually not incredibly popular. Mostly because this is a cellphone game I think. People want to be able level on their own time. One of the reasons that I play so much is because I can take the game in my pocket with me wherever I'm headed. (really hoping to do a video playing in the ocean well I'm here in Hawaii if I can.)
Also on the subject of group Lvling, because Druids don't do as much damage as quickly, there are times they won't be the first people to pick for a group. They are the best in the game for helping other people survive meaning that there should be a high demand, but the survivability needed for leveling can be obtain just by using items from the Platinum shop which most people do. These items can be purchased from other players who spend money on Platinum, so they're plentiful during certain times and people often stock up and then level that way. At bosses Druids are incredibly necessary because you need both the bus from Madrid and the bus from the Platinum shop to take out the boss but why would one, one of the other will suffice. Leveling with one DPS in one Droid gets you more total XP, but it doesn't get each person more XP. this means that while it's cheaper to level with a Droid, it's faster to so level without one
Well that was very informative and useful text, thanks
