i hate charges, tried it once when the Expansion first came out and never touched her again.

And Assassin charges are my favorite builds. Ever since they were buffed, the charges became very strong.

Last patch, the downfall of charges was that the sin was incapable of staying in melee range of a boss to charge them without being destroyed, making the sin pretty much useless. I'm hoping that, if going tanky, a sin should be able to charge in front of a boss without exploding now, with the changes that have been done to boss difficulty..

Can you modify phoenix strike so that when used it stacks charges from all charge skills (if you have them) like if you have them all it adds one additional ball on each strike ?

If you have them all you hit 18 times and and get 18 balls or 7 times 7 balls. You get me

I'm not aware of a modding method of attacking with PhoenixStrike but then earning CobraStrike (or another skill's) charges, if that's what you were intending. You can switch charge-up skills to add more charges already though, and your finishing move uses all charges that have been stacked. If you've already attacked 3 times with PhoenixStrike, you can switch to CobraStrike and attack another 3 times, and cycle through all the charge-up skills you own before using a finishing move.

I wouldn't recommend that in HUv1.7 though, since more charges aren't necessarily better (usually charge 2 and 3 are more related to AoE damage, which isn't higher than just quickly using a single charge against a single target). It's not a bad idea to get 1 charge from a few skills (maybe 2 or 3 from CobraStrike for the dual leach that's level invariant) and then Finish.

The idea is not to switch between so many skills and gain them tru just one - phoenix strike.
