Spamming "LF2M HAMMER NEED HEALS FULL ON DPS!!!!!!!!!!!" over and over again at fleet, and having to see it in chat, is NOT fun. I agree there are Pros and Cons to the LFD tool, but I think it is better then having to spam for thirty minuts to find a group.
I am on Ven Zallow which is a highly populated server, 150ish people at fleet during primetime usa. Still have to spam forever to find a group.
Hence, I support the addition of a LFD tool.
