Excuse my typos, on my Kindle... I find the best server to be RP servers. They tend to be more mature (in comparison) and it friendlier. Even on the notorious Moonguard I find people to be more helpful.
Last week I server transferred from Akama to Wyrmrest Accord. I am playing with the idea of rp'ing, but have not decided. Unfortunately I do not know anyone on my server except for the people in my guild... and the guild I am in is a "grinding" guild... there to help you as you level, but people usually leave to bigger better things.
The downside to RP servers is it is hard to find a guild. Because of the attitude most people have towards RP in general guilds are not as forthcoming. For WA, at least, there is an up to date site devoted to active guilds on the server... that being said quite a few require an application. WoW is serious business, lol!
I loved Akama, but with the cross servers the world Pvp is a little out of hand. It is not so bad as 90, but when you are a level 22 trying to kill spiders for a quest line in Darkshire and a hunter kills you not once, twice, but 5 TIMES! That is a little ridiculous.
I recently had a rogue camp me outside of Booty Bay. I jumped on my 90 lock and ran out to him, requested a duel. Of course he declined, said my cooldowns makes it a win for me. Whatever. Then he said how there was a hunter in the area he was camping (me) trying to make it sound like he was camping a 90... my hunter is level 33. But I digress....
Long story short since I am a bit burnt out on Pvp I transferred my low leveling lock to the RP server, and the stress has been lifted, lol.
Terra is suppose to be a good game as well, and of course Skyrim mmo is coming out. I wish there was an SI guild... I would so join.
