@entropy What do you mean by stats? As I see it there are no universal stats for a given TF. There are levels and overpower as well as accessories but these are user controllable e.g. all of my TFs are at least at level 15 and all of them have all the accessories.
Squads and promotion are important concepts because much of one’s success depends on promoting the right TF(s) in each squad.
Viability I probably get, e.g. a TF has to survive a level 350 spark run.
This game isn’t for fun anymore but performing this or that.
Anyway, any TF which is maximally promoted should be in S tier. I have the following
- Hound
- Blaster
- Superion
- Nautica
- Dead End
- Warpath
- Ultimate Megatron
- Grey Slam Grimlock
- Breakdown
I would exclude some of fully promoted TFs if they are simply promoted because they are first in a squad but I don’t have those.
The F tier includes those that are good only to use in missions, like Bumblebee, Heatwave, Jazz, Ultra Magnus, Prowl, Arcee and the very “funny” to play C/Grapple.
