As a monster main I have to say this: Evolving is too short. There is nothing any hunter team can do about it to punish it. You can come with your yadda yadda, but the simple answer is no. You will not magically fool a high level monster with a mysterious cloak.
You will not time your enemy evolving within a margin of 5 seconds. To be frank the whole process is gimped. You don’t need stealthplay at all due to vastly superior speed compared to the hunters you can just beeline straight for high density food areas and are reliably at 50% to stage 2 when the hunters touch the ground - mind you still a far distance out.
Then I can proceed to eat on the move the last remaining 6-8 meat since touchdown proceed to move further away and press evolve. At worst I will be domed, but even that is a 50/50 at best.
If you are extra smart you will evolve right next to prepared meat and even if you are domed you will still be able to feast up to half armor before anything major happens.
If you do not believe me just play enough until you encounter the top ranked players. The only way they get domed at stage 1 is, because they actually don’t care and rightfully so.
Since getting domed against your will is getting rarer and rarer these days I would suggest to mix this tweak to a basically guaranteed dome unless bad luck or very stealthy play is involved.
