I am aware that there might be a lot of similar discussions about that matter, but the more we will talk about things the more likely they will get changed.

Remove (at least Nerf) the Champion System:
From decently balanced 1.5, we have come to relase of the problem --> 1.6. I am not saying that CPs were entirely bad idea. Tamriel Lore always had some taste of star constelation I respect that. The game itself had rewarding difficulty level but the more CPs I was gaining the easier game was getting. On the very begining of that operation it was like 400k exp/CP (for those who are relatively new), it required some effort, resources and knowledge to grind effectively. Good player were getting even better, the punishment they were able to represent, these cost reduction, those resists, man. I liked it myself, but guess what, pugs crying, dmg is too high and stuff, okaay. Next patch, bring first nerf due to that, Battle Spirit changed to 50% reduction hmm..., easy way to balance the game ha? It was first failure of the CP System.
How about second? We didnt have to wait too long, CP cap with Orsinium Patch. Reduced good players population a bit, what would u do after grinding entire days to get 1000+ CPs and suddenly got it cut by half? CPs got easier leveling system that wasnt good thing either.
Here we are, MoL is getting released and due to cap, Zenimax started making changes to constelation. Merging Magic to Elemental Expert side hmm... why would u cap something with purpose of reducing damage and then buff certain classes like Sorceror with this? Consider it as another failure due to lack of logic (pugz crying is irrelevant at this point).
Dark Brotherhood, this, this... this patch is when game started collapsing. Trait changes, heavy armor buff, Viper, poisons, it definitely wasnt good for the game, but what was going on with CPs meanwhile? Well, not directly with CPs but with certain skills damage type changing. Incap Strike, ganker's best friend , skyrocking DK's DPS (flame to poison changes), hurricane for Sorcs. Well so we are having buffs again, who wanted that? Due to lack of recent CP changes u might think that they are balanced now, are they? No.

Ultimate solution: remove Champion System.
Viable solution: reduce the amounts in blue trees from 25% to 5%, cut reductions down to 5% or less in green trees, same in red trees down to 5%. Also bring back certain damages types/reductions to original spot. Remove the cap. Lower values, makes lower impact, what makes game more vurnelable to balanace.

CPs are not the only issue of the game, but its definitely the biggest one. This is what I come with, after playing the game for some time now.
Sorry, if I made something hard to understand, I am not native English speaker nor writer.
