I agree with your suggestions, this would be a good change to implement next patch along with the promised research bonuses for new nations. For balance reasons I could see either the conversion rate being higher than 10 SL/RP or the rate of convertible RP earnings being slashed.
Maybe another possibility for CRP would be using the points towards squadron vehicles or some of the lower level premiums (rank IV and below) that appear on the Warbonds shop.
i have so much squadron vehicle to unlock and it take so long because unlike normal TT vehicle you can only research 20k every 3 days, pretty limitting
Honestly, this is something the game badly needs as a part of making CRP usable w/o GE. I can count on one hand the number of times I actually used a little CRP with some spare GE (skipping French Rank 1 tanks initially on release being most of them).
+1 Definitely CRP should be able to be used with SL. Maybe not 10 SL → 1 RP but something like 5 SL → 1 RP. With 10 SL → 1 RP. Let’s use the F-4F ICE for example, with 10 SL → 1 RP the research cost would be 4.2 million SL CRP cost + 1.12 million SL purchase cost + 320,000 crew cost bringing the total to 5.34 million SL for one vehicle which I think is too much. If the rate is 5 SL → 1 RP then it would be 2.1 million SL to convert CRP which would bring the total to 3.54 million SL total which I think is a bit more fair.
We should actually rally for this to be added IMHO. Its a very useful mechanic and no one uses the GE exchange for it anyway so that would be one of the greatest additions of all time.
