That wouldn't be best that would be the slowest with a 1 charge move but significantly faster than 2+ charge moves could get. Absolute best right now would be every 40 seconds 45 if you are meleeing and don't want to swap to a gimp weapon. Though with the charge system it ends up averaging a little better. Add on to the fact it says they are making them accumulate faster and making them stronger and give them skillchain properties it might not be too bad. Imagine this you and your pet tp for say 30ish seconds, you use ready and let's say it does 3k dmg, then you use a ws (which one will depend on elements of course but a lot of the axe ws are of similar strength now) for let's say 6k dmg followed by a 8k skillchain. Snarl the hate off rinse and repeat. It might not be the sam non stop skillchaining or the thf super huge ones but would be interesting and possibly good.
As far as just general dps one big thing they could do is well first make that 1 acc jp more like 2-3 and then finally expand them to 30 like they said they would. That would be huge for jugs
