Please no. Not everyone is trying to rush to cap. I like the solo speed exactly where it is, if not slower.
I also agree that grouping should be more lucrative than soloing anyway.
Are you guys serious? Solo EXP is already PRETTY DAMN FAST with leves and guardian's aspect. What do you want? For it to be as fast as a group EXP party? Lv50 in a day since a week is way too long?
Don't convince the devs to baby this game up to cater to your 20 minutes of playtime per day please. You can complain about EXP rates in 2004 FFXI but definitely not in this game. It's easy enough as it is.
Soloing options exist in all MMOs and should also exist here.
MMOs are almost exclussively designed with endgame partying in mind, not random 1 mob at a time field mobs.
I support AOE abilities, links and solo chaining.
I don't see how soloing is a problem can get 1-20 solo in mere hours. If anything they need to just make leves more fun like escort missions and other things but i just think leves are daily fodder quest which gives you good exp if you waste your time on them.
