I'm currently sitting at 275 CP. Yes, that's low, but after the first year I left and have recently come back. When it comes to PvP I have four options...
1. I can play standard CP.
2. I can grind CP so I can compete in the CP campaign.
3. I can play no CP.
4. I can simply not PvP (or just quit the game all together).
Let's briefly review the 4 options.
Option 1... No one likes being severely handicapped and getting beaten down because someone else has played more than you, not necessarily because they are any better. This can not be solved with L2P, different builds, etc. Option 1 is not appealing.
Option 2... I hate the idea of spending tens/hundreds of hours doing something in a game that you don't want to do just so you can end up doing something that you want to. So, option 2 is not appealing.
Option 3... I enjoy the levels of sustain with SOME CP. When entering the no CP campaign the game feels too slow and sluggish as the levels of sustain are not fun for what the combat should be in a fast paced MMO. It is apparent that ZOS has balanced around CP, so the no CP campaign just feels incredibly off. This will only get worse in the Morrowind patch.
Option 4... Honestly I'm leaning towards this option at the moment. I'm tired of playing against people with over double my CP and with far higher levels of sustain, damage, healing, mitigation, etc.. These people with a clear and distinct advantage kill me and emote/teabag my body and think they are good... Nope, they have just played longer than me and have been "rewarded" with much higher power levels. Just because you have spent more time doing something in life, doesn't mean you are better than someone who has spent less time doing the same thing.
I have my flame shield up for those that will post L2P, bye, suck it up and play the no fun no CP, or other stupid responses... But I'm sure your higher CP will ignore my shield
