I totally agree with most of the points the market always concerns almost same pokémons and in the events it's almost the same pokémon which is hunted because of either their awesome spawn or because the popularity of the pokémon.
The other point that I find interesting is about the 4 acc I wish the maximum was 2 but I guess it's too late to Change it.. Doing bosses solcaleon digs supcious bot etc with 4-8 accs is questionable if it really makes fun or is only to get the most awesome stuff. Those boss spams with 4-8acc made the encomy how it is now and people wonder why it's hard to sell stuff for similar price as few months ago ofc it's the reason that people can't spam so much anymore. Doing each acc 50 bosses gives already 1m imigane doing it with 8acc + pve coins + items /pokes. If we count that together you could have made over 20m just in a month just by bosses (no supcious bot / digs/solcaleon counted)
