Hello.
Recently there was a thread about Blizzard's Tom Chilton regretting to add a 3 difficulty system instead of two in the current expansion. I assumed he meant by easy/normal/hard. That would make perfect sense since it can cause a lot of problems with the people whining and thus cause Blizzard calm down with the constant nerfs to normal modes. Obviously easy modes should reward blue gear but that. Anyways I read somewhere in that thread that someone posted about Blizzard thinking that they wish they can make raid sizes 15 mans instead of 10/25 mans. Even if I was just imagining it or it was just some quick thought, I honestly think it would be a good idea for raid sizes in next expansion to become 15 mans instead of what it is now and please, lets think honestly about this, this could solve numerous balancing issues/comp issues/class stackings (relatively speaking with in 25 mans it is easier to class stack compared to 10 man) and possibly lag issues (depending if you're in 25 man). Example is that 15 mans can require a comp that is in between the requirements in 10 mans and 25 mans. Another is possibly 25 man guilds splitting up or leading to 2 15 man groups since most 25 man guilds (from what i've seen) have over 30 people logging over all the time, and 10 man guilds just need to find 5 more people can be much more calmer about finding the best comp for x boss. Only downside I see with this system is that guilds could possibly break up but really, people thought the same thing for Cataclysm but that barely happened (at least from my experiences, again being biased here).
Thanks for the thoughts/reply.
EDIT: NOT adding a new raid size in next expansion but removing 10/25 mans for solely 15 mans.
