Decided against my better judgement to do a multi on the STR banner, and got SSj3 Goku (GT) who I was really hoping for, and STR SSj2 gohan (dupe) as well! Now, time to try a STR nuke team for this WT, and hope that not too many people are running AGL mono teams (I didn't see too many in the last WT, but we'll see).
So... I'm rank 22 and my Omega is level 48. Should I do the SSR pull (the one with Goku, Gohan and Piccolo), try and get Gogeta or some other character?(I have 110 stones)
Also, to raise The super attack I need to get another Omega and "feed" it to my main one, right? That means I need to get 10 more before awakening him?
I'm enjoying the game but there's SO MUCH stuff going on lol. I haven't done any events either and don't know if I should or why I should lol.
I'd recommend doing 2 more multi pulls on the current Dokkan banner to maybe get SSj3 Vegeta or Gogeta, since you would be able to breeze through all of the story missions with those. The starter SSR banner characters aren't that good, but they can be helpful in filling your team since they have a low team cost (keep in mind that you can buy these in the later part of the story from the Baba shop, so don't worry if you don't get the one you want).
For raising the super attack, you either feed the same card like you mentioned or you can use Elder Kai cards, which mainly come from missions, world tournaments, or special pulls (like the current STR only banner), and are very valuable, because Elder Kais raise the SA of any other card in the game. You can awaken cards normally (SSR-> UR) and still use the same card to level their SA, but once you dokkan awaken them (i.e. their name changes), you'll have to use an item to temporarily un-dokkan them to raise their SA using dupes. There's a new dupe system coming soon to global, so it might be better to just hang on to duplicate SSR's for now instead of raising SA.
Yeah, it can be kind of overwhelming at first. For now I think you can just go through the story until you feel like you have a good team, do some strike missions occasionally to get more characters (these rotate daily), and just experiment with the game in general. Most of the Dokkan events aren't necessary until you've completed the story on all difficulties (although they do help a bit), and they require really good teams, which you might not have ready until rank 120+.
