The JAS39C is at 420k RP to research.
That would run you 9333 GE (or just above 60 EUR) to unlock the vehicle and then you wont have the modifications unlocked or the RP/SL-boost that you get on a premium vehicle that cost just about as much (or any of the bonus premium account and GE the pack comes with).
Edit:
the only concern i have with the main suggestion is that people are not going to buy SL crates anymore as it wont be worth it even in the slightest as the CRP is WAY more worth the spent SL.
Right now, the best bargain gives you about 433 SL per GE. Going by the original suggestion of 10 SL per CRP and the current rate of 45 CRP per GE, that works out to 450 SL for the amount of CRP purchasable for 1 GE, which is still higher than the best SL/GE exchange rate, so it works (i.e. it would be more expensive to exchange GE into SL and then buying CRP compared to buying CRP directly with GE). Of course, knowing Gaijin they would probably make the ratio much higher just to discourage F2P and encourage buying GE, but I’d be fine with a ratio up to 20 SL per CRP. Of course, if Gaijin also reduces the GE cost for CRP (which they should, as many have said here and elsewhere), these calculations would then need to be revised.
I’d also like to see CRP being used in other places (e.g. researching modifications), but… that’s for another post.
Really good suggestion, as to earn those large quantities of SL you have to play a lot or buy them with GE. As Oshida mentioned, this would be super usefull when starting a new tech tree - you could create lineups for ground and skip biplanes for example.
I would personally like to see this option for researching modules, - I dont mind grinding out 400k top tier vehicle, but when I finally get to play it, the stock grind is absolutely terrible (even after the changes that Gaijin has made). For modules the SL/CRP rate could be obviously higher.
The SL/CRP rate could also be rank-dependant, but that has its own pros and cons too (e.g. i dont know if I’d want to pay like 1M SL for a biplane, afterall I dont have much SL xd).
gotta be honest I rarely if ever use convertible RP for this exact reason. The conversion rate is pathetic. Normally I’m more polite about this but convertible RP as it currently stands is a rip-off and that’s coming from someone with an insanely high tolerance for overpriced video game content.
With the overwhelmingly positive poll on this suggestion gaijin basically HAS to do it or risk potentially getting reviewbombed into submission again xD
Someone else made a comment about it, but i think that it would need to be a different suggestion altogether, because modifications doesn’t use CRP, only GE (based on CRP Cost iirc)
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
