I've got 5* Ghost sitting at Rank 3. I also have a Tech Awakening Gem courtesy of the Summoner Appreciation Calendar and just replenishing the T4B required to take her to Rank 4. I have Wasp at 5/50 and both Ant-Man and Hood as unawakened 5*, 2/35 and 3/45 respectively.
But one thing's holding me back from either the awakening or the rank up...I suck with her.
I understand the THEORY of how to utilise her phasing - both to cleanse DoT's for Fury, getting the crits in regular attacks and especially with her specials (made easier with Wasp) - but I just can't consistently put it into practice, especially in difficult content. I tried to use her v Claire Voyant last EQ and I think my best effort only took 50% of her health.
I'm an average player - capable of some solid fights here and there, soloing Mini-Bosses and bosses etc, but can also die to an equal-rated opponent in Arena and couldn't manage to get through the latest Boss Rush.
When I try using her my phase-attack attempts are constantly either blocked or even intercepted so I'm clearly getting the timing wrong.
To that end, any guidance or links to guides would be much appreciated, as well as specific tips on how I can improve this (other than "git gud" of course, cause that's a given

)
Also would you consider it still worthwhile pumping the awakening into her (got enough sig stones to get her to about Sig 50 with tech stones and even to 100 if I used generics) right away while I practice, or wait to see IF I can get better before the investment

Finally - any recommended training opportunities to get better with her? I've heard RoL Winter Soldier isn't a great training dummy for her because he's not aggressive enough?
Much appreciated.
