Sorry, but i disagree entirely. 8th is infinitely better than 7th and there isn't even close to the same level of abuse. More armies are competitive, more models are competitive, and the tournament attendance (and results) shows that.
GW has posted monumentally higher sales numbers, so I don't think its fair to imply that people are leaving the game at the same speed they are joining it.
8th is the healthiest 40k has been since 5th edition, and as someone whos played since 3rd, i'd argue this is the best 40k has ever been.
If anything chapter approved proves its NOT open to as much abuse... considering they are making active balancing changes. I don't understand how the existence of a balancing document somehow indicates a game is more abusable.
I also don't understand how Seraphon need a refreshing considering they are stronger than they were in 1.0, just got an incredibly strong mechanic in 2.0, and have one of the most diverse range of models under 1 allegiance ability. Perhaps that will shift after Kroak got nerfed, but we'll have to wait and see. I wouldn't be opposed to a refresh, the new SCE and Nighthaunt books are awesome and the models are beautiful, but i dont think we're on the short list of allegiances that need one.
Sorry to get so argumentative, but comments like that can really create a negative (and in my opinion, untrue) opinion of how healthy the community is. 40k is more popular than ever, and any opinion to the contrary is just that, an opinion.
