How is Attunment Recharge Rate Weighted?
I don’t think you can compare Attunement Recharge Rate to these stats. It buffs everything an ele offers (damage, defense, heal and so on) and is pretty much like all these stats combined. That’s why it is so important for eles. I would prefer a high ARR over the other stats any time.
All the stats you mentioned are not equally strong. They are affected by certain ratios. For example:
1 point in Vitality = 10 HP
1 point in Precision = x damage
The damage 1 point in Precisions offers can be more than 10 HP or less. This means you can’t really compare these stats 1:1. They are all strong in certain situations but most likely never equally strong.
P.S.: Don’t don’t forget you also get free Boon Duration and strong traits if you put 30 points in Arcana.
They may not necessarily be balance with each other but, the devs weigh them the same on gear and traits.
It’s complicated OP, even more so because attunement swaps with points in arcana can proc effects with swaps and dodge more often such as healing, protection, condition removal, dps, etc., and some of those effects can be on the party as well (support). Faster attunement swapping also affects skill combinations and what skills are being used and the weapon used is an additional variable there. Sometimes the lower attunement cooldown can seem to be or is wasted with many skills still on cooldown when going back to an attunment too early.
I think to a great degee it comes down to how much survival you need for what part of the game you are running with that character. How much damage you can live with and be happy with results. How much and what party support you feel is appropriate. Most importantly, how you like to play. You will find many builds that already have put all this together and favor certain weapons and play style. Or you can put your own together.
There was talk a long time ago about the devs having some predesigned builds. We may see that some day. With the ascended gear, we are already seeing a reduction in build choices since not all exotic gear has an ascended alternative. The advantage of fewer allowed builds is the fact it becomes very hard to mess one up to the point it is useless lol. You will not find an item with crit damage that does not have power as the main stat for example.
