I didnt know paras had worse RA than riflemen
That makes absolutely no sense. That should be addressed first before making any other changes.
Also, I really don't think moving them to CP1 is the right call. Thematically paratroopers aren't.... well paratroopers in this game. You drop them safely on your own territory and use them like front-line infantry like riflemen.
In the first CoH you could drop them in the fog of war, reinforce and upgrade them with recoilless rifles in the field.
The first iteration of the commander had the pathfinder/beacon gimmick that really didn't work out, and it hasn't been touched since they made it "safer" for paras to drop without them. IMO it's just another forgotten commander.
You can still deploy paratroopers in the fog of war, and it is occasionally useful, taking an unguarded point or something, just that lines of battle are usually drawn by CP3 and you're probably going to land on a MG42 bunker or something horrible lol.
RA wouldnt be too huge an issue if you didnt have to fight until vet 3 for it to get any better, which means Paras will be very bleedy at the point which they now arrive. Their veterancy is actually exactly the same as Ranger vet, which works for rangers since they spawn with 73% RA or something, but not so much Paras.
