Not that I disagree with your point, but maybe check that math again because you switched numbers.
45 mun is 60 MP in that conversion making the WC51 260 MP.
We can also use other (rough) conversions, such as standard mines killing 2 models maximum (~50-60 MP). This gives an approximate conversion of 1 MP being worth 0,5-0,6 mun.
The WC51 is quite a niche unit though. As already said, I don't know if anyone at a semi serious level plays this unit outside of 1v1. Like most of those super light vehicles though, they need their space and they don't get much in team games. But maybe that's a plus for balancing it if we don't have to take care of larger game modes.
Yea I definitely swapped the numbers. That's my bad. I don't agree with the mine trade though because mines primarily are as a snare, not mp bleed and the model cap was in lieu of spacing changes. It's not so much a hard ratio as an accidental one.
Check the math.
While i can't find any source, i remember that Relic valued mp/muni/fuel at a ratio of 1:3:5
It's not that resource conversions work that way, it might had been how xp value or something was assigned.
I do recall something along those lines however that was at a different stage of the game when resource conversion was all over. Now that there is but a single way to convert (I don't really count the soviet one since it has other variables and also doesn't include all resources) its easy to calculate by that standard metric.
I'd say it's roughly accurate too with mental applications without the conversional math as well. If I use 30mu for a nade and (outside a strategic use of course) don't kill at least 2 models I feel it a waste
Anyways. Is the wc51 over performing? Probably. But is it worth less than a kuble with the munitions upgrade? Certainly not. Even with my bad math it was worth more and any metric of resource conversion puts 45mu as worth more than 10mp.
