Quoted from Gentax:The more I play AIQ the more I see I'm in a very "weird" position. For the first time I have a table where I can hit everyone shot with 70% accuracy AND I know the rules and strategy. However despite this, I only can finish with 40 million a game. I don't wanna say I'm "cursed" but I get weird things like I would "thud" the disk multiple times a ball or how a ball with bounce off my flipper, hit the sling then drain. I'm before I used to hit standups and drain but now I don't, I hit the shots I want and don't kill myself from a bad shot, yet my score or my gem count has not budged.
Concentrate on the basics and a repeatable strategy.
Pick whatever your easiest 2 shots are that count towards combos and keep trying to repeat those. Probably Black Widow and Captain Marvel or Gauntlet ramp.
Just work on those shots until you get 4 combos to earn a portal lock. After you get at least one portal lock either hit Thor once or twice to get that multiball ready or go ahead and start a gem quest.
Pick whichever gem you are most comfortable going for. Reality is probably the easiest... spin the disc, shoot your best ramp/combo shot(s). Rinse and repeat.
If you bring in the Thor multiball, chances are good you will finish Reality gem and have over 100 Million points. Iron Man multiball is also good to bring in to a gem quest, but can be harder to start than Thor multiball.
Once you can do that fairly consistently, add additional shots or gem quests as you improve.
