What's the practical limit of CP, though? I'm at about 1270 on my main character, and starting to run out of perks to spend them on.
I use pretty much entire green tree and I don't have enough to buy war mount on this char, but other's use it instead of thieving or fishing. That's CP3600
Jack of all trades addon slots stars on the fly, so I don't have to think about slotting them myself, I harvest a node, it slots plentiful harvest and master gatherer, I loot urn, it slots homemaker, I Approach crafting station, it slots disassembly, etc... I'd go bankrupt if I had to pay every time
Similar with other trees, Dynamic CP addon can reslot as needed depending on where I ported and my selected role. I.e. I use different stars if I am in overland, dungeon as a healer next, and port to Cyrodiil afterwards without me having to remember to reset and redistribute in between. Obviously, I can do all content with same generic set of stars, but if it costs me nothing but setup addon just once and never have to worry again, that's very useful.
Without addons it's indeed probably mostly useless, if you have to go to menu manually every time anyway.I craft about as much or even more master writs long after I reached CP3600, CP is just byproduct of making vouchersby far not worth the time to level up.
It definitely saves a lot of time and gold in long run.
