Need some help
Hey guys. I have recently started playing and yesterday I opened my first 4* hero crystal and got an OG Megatron. Now I also have 3 more 4* bots: Prowl, Soundwave and Windblade. All of them except Windblade are at R2. Question is simple: Who should I bring up to R3? I have the cats, the "iso", everything. I myself really enjoy playing Megatron. What do u guys think?
