I think that there is a good argument to be made that the 163 is too cheap. When perk values were adjusted this month, the fact that the 163 is only available at a few fields was not weighed into the analysis. It's not apples to apples when comparing it to other perk planes because it is only taken up when there is an opportunity to do so. When there is an opportunity to use it, its take rate is much higher than stats would otherwise indicate.
if the 163 is available no one even bothers to watch or patrol the strat area. they wait till the red darbar is near the city and are up at 40k in 3 min.
the 163 should be the last ditch choice and not a complete substitute for actual air cover by piston fighters of the strat areas.
it should be so expensive that few would risk losing so many perks to use it on every single red darbar dot that passes along.
a good 163 pilot can wipe out a set of b29s at 1.0eny thats 300 hard to get perkies.
why doesn't the 163 cost 300 perks as well?
think about it.
you dont encounter many b29s in maps where strats have a 163 base because the b29 pilot knows he could encounter a swarm of not just 1 163 but 5-6. and if he kills them all they are back and attacking in 3 minutes because 50 perks to most who know how to fly a 163 is like upping a t34/85 at a spawn camp. they dont care if they lose 50 perkies.
the b29 and the 163 are the ultimate enemies in this game and both are only useful at the strats. the b29 takes too long to climb and its bomb drop pattern is to large for precision work that the other 4engine bombers can do better.
300 perks for b29s 300 perks for 163.
nothing less will even deter the cloud of disposable 163s that up repeatedly anytime anythign to shoot at is in range.
