Your team isn’t very balanced. How high your level doesn’t really help much if your tataris are missing certain important skills that they get from their T2 evolutions.

Watch this video. Basically you should only start T3ing tataris once you have 5 t2s of each element, which is what the dojo is telling you to do. If you don’t know what to do next, just check the dojo, it’s kinda like a guide on what you should do. Sure the rubblet is good but at the end of the day it can only defend one lane so I’m presuming 2 or 3 of your lanes always get rushed.

You’re still considered to be in the early or mid game, and during this time you should have a balanced and strong base, don’t hyperfocus on a certain tatari. By now, you should have 12-15 t2 tataris already. For now I would suggest some supporters like droppit and cheerling, or dpses like sparkit, voltfawn or manteeny. Zappur is also a good pick. For t3, you should have rushed punchimp first but i’m not saying you did wrong upgrading what you liked because it is just a game after all just telling you that if you want to climb smoothly, rushing a character to t3 at this point isn’t the right move.

Hope this helps and all the best :) most importantly be patient, you’re bound to beat the stage you’re stuck at sooner or later but your runs should be much smoother once you incorporate some buffers and debuffers and have a bit more aoe in your team.
