This post was not intended to convert questers into grinders. It was intended for people who like me get tired of questing alone after a few hours, and wish to join a group and go a murderous rampage for a while. Many grinders are losing hope that this game will be good for them, lots of talk about not playing and or canceling orders. I wanted to offer this substantial ray of hope to them. I am a grinder and I will be playing since grinding is not dead. And below I provide some proof.
Just before the end of the beta I ran a few experiments on experience gain to see if grinding was hopeless. Here are my findings and they suggest that solo grinding will be terribly inefficient but group grinding is viable.
My character was level 12. When solo killing a Mob 8 levels below exp was 0. When killing a Mob 4 levels lower exp was apx. 60. When killing a mob 2 levels higher exp was apx 60. Thus we see Exp reward is little influenced by the level of the Mob (if at all) with the exception that too low (and likely too high) offer less or none. Naturally loot scales up with Mob difficulty but the exp appears not to.
Next up was exp sharing. Solo mobs gave 60. Killing a Mob with another player (not grouped) also gave 60. Killing 3 mobs in a tangle of players all blasting them gave 180 (60 each). Thus we see that you lose no experience at all from sharing kills! In fact no matter if I had done 20% or 80% or the damage the reward was consistently the same.
At 60 exp per kill I calculated soling would take a substantial amount of time to level, about 3 times as long as speed questing. However in a group of four (gaining grouping bonus) you could kill the Mobs 200-300% faster than you could solo (depending on MoB density in the area). Since group killing does not impair the exp gained per kill the grinding time will be substantially reduced to level.
Now speed questing could probably still outperform this exp gain, at best grinding would probably approach 70-90% of questing exp gains coupled with exploration from questing. However Dungeon grinding offers vastly better wealth and loot, so it seems a fair trade.
