Apparently they have flown the Wildcat simulator in Brunei conditions and the feedback was that it performed a lot better than expected.
ISTR they claimed the Lynx could work in Belize to replace the Puma, forced the RAF out and then discovered the Lynx was no good in that environment.
And just because a simulator says it will work is not that much of a recommendation.
BERP blades and tight jungle clearings are not a good mix.
