This has been discussed since the release of VOA, and today I finally had enough as well. I have already gotten my rogue to T5, and I'm currently working on my druid... I get that the point is to make players play for longer, but these dogs feel like a total waste of time. I WANT to do them, but I'm often too annoyed to. I wish I recorded my gameplay earlier today, because it's almost unbelievable! TWO entire lixes resulted in ONE damn 2 star dog spawning. This isn't the first time I've experienced this either.
Please increase the chances of 2 stars spawning in every area. The levels of the dogs matter as well, since many of us are trying to level up while doing daily quests.
