As many players do not fly in special events
Actually, there are very many people who fly in special events. There have been as much as 600-800 people participating in FSOs in any one given Friday night. Scenarios are also quite popular, with numbers in the 300-400s, as well as Snapshots, which also numbers in the 200-300s.
and those that do might sepnd only a few hours a week in them
Does it matter how much use it gets in the MAs? What about the Early War and Mid War arenas? There are plenty of people who fly in there on a weekly basis, myself included. The He-111 will see a lot of use. Especially in special events, scenarios, and FSOs. Not to mention it would be a good bomber to rack up perks in the MAs.
I think most would rather have the HTC team devote their time and our recources towards something that might see more use.
Like what? He-111 fits the bill just fine.
