As someone who has been playing on Classic for 2 days now:
I can't team up, all chats are disabled to be used below level 29.
I must dual box for buffs, cutting leveling speed in half.
I can't sell stuff for decent adena, getting D-grade gear is out of reach. Hopefully I can get a dualsword D-grade by them time I'm level 40 and should be using C-grade..
I can't find a clan because I can't use the chat.
All starter villages are empty. Seriously. Empty.
All towns are ghost town except for Giran, which is near to empty.
