I feel like I've hit that wall of git gud. Started playing this game a few days ago. Rolled Horus as my leader. Not sure if it's because my subs suck or I suck (probably the latter). His leader skill gives 4+ attack bonus when 4 colors are matched up on the same attack.
Easier said than done. I can hit that bonus maybe 1 out of 3 tries. I've looked up a few guides and they mention how easy it is and it's just a matter of practice. Any Horus/rainbow team players want to shoot me a few tips?
Rainbow leads are not easy. don't believe any guide - specifically in the early game without optimal subs,awakenings/time extends, and board changers it is very difficult.
Granted I can't talk much about the early game now, but the difficulty ramps up after a few day of play to make early rainbow teams very hard to play.
now after saying how difficult it is, I feel it is one of the best ways to learn how to play well - even playing a rainbow team badly helps you learn to look at the board and learn how to combo better.
what to do?
It might be worth looking up re-roll lists - there are easier leads to roll for the early game and if you are low rank (less then 90? - its really easy to rank now) - consider starting over. while it might seem counter intuitive, I think ranking and getting more stamina per day is one of the most important aspects of the early game - it affords you more game play and more attempts at content.
as mentioned - partner selection can be very important and you might even consider pairing with non-rainbow leads to guarantee at least a 3x multiplier to carry you through content when you don't hit your 4 combo.
Look into multiplayer - I hardly use it myself, but if you know a high rank player, running multi on monday can rank you extremely fast.
try not to take the guides too seriously - in my opinion, the early game is still the most fun.
another thing - are you going to spend money?
non-iap versus iap players look at the game differently.
I lasted about a year before I started funneling cash into this beast, the one thing I would do differently is I would have re-rolled for a better starter (I ran Loki!)
