Linc thank you for this post. I am really disappointed by the response you got from some of the testers and the admins comments were the worst. I think that saying "there are warlocks" and "it makes world pvp less likely" are terrible reasons.
1. It allows you and your friends to not have to RELY on a well placed hearthstone, 10 + minutes of travel or having a warlock AND 2 other group members in a group to get a summon or to meet up.
2. Just because there is a class doesn't mean they are all dedicated to that single aspect or move..some won't summon, some won't have stones, others just won't be online or accessible.
I am joining this server with roughly 10 of my friends and we come from ED where we play 6 hours every Monday. We love all that is Vanilla but being older...with jobs, lives, ect ect we find the travel time / time spent rezzing or traveling to be extremely daunting and it really kills off a lot of playing time. I can understand people who don't have any RL friends they are playing with or just log on solo and for the most part play solo but for us (and I know there are more like us out there) we are playing because we get to play together and do all sorts of adventuring and pvping together...and that is really challenging when you again take 10-30 minutes to just meet up.
Again I would really like to see less die hard/try hards complaining about sticking to everything that is blizzlike and being a bit more creative but in their defense we did sign up for..*sigh a hardcore blizzlike server I guess.
