First of all, no. There are various groups of players who will not be able to find guilds that fit them. I listed a few of the types above. If you only play the game once a month, you will probably not be able to find a guild that is active enough to form groups and that won't kick you while you're inactive. If you speak only Portuguese and play on a North American server, you may not find enough players who you can communicate with well enough to form a functional guild. If you have poor impulse control, no one's going to keep you in their guild and no one should have to. Beyond that, the always part of things is important. Very few people always solo. Many people who solo sometimes or frequently also group, and many of them are also in guilds. I've been soloing on and off all day today. I'm home nursing a nasty sunburn, but most of my guildmates are presumably outside enjoying the summer weather. Last night we grouped and leveled alts, though. A few days before that, I was soloing again because it was 2:30 in the morning and I couldn't sleep. See how that works? I think that's a very common case for players. No one is crying about PUGs being mean. Shudder. PUGs are generally full of nincompoops who don't have half their class's abilities on their bars and people who are terrible for the sake of being terrible. There's no need to cry about them, because I don't play in them.
