To say that TOD requires forcing players to go back through training due to reaching an arbitrary number of deaths or grievers will populate the game and make everyone else miserable is pure assumption. One that has yet to actually prove itself out.
I don't know Arlo, I'm not a "strat" guy but you sure hear a lot of wailing about people who are not following mission orders on both channel 1 (and now vox) and the bbs. And there is the otherwise dweeby behavior and gaming the game actions that take away from historical immersion. If you want to have it as an option, fine, but I have to disagree on how long it will be before it is turned on. There is just too much evidence to the contrary. Examples (daily? universal?):
-- I upped a goon like they asked, but then they were off vulching instead of protecting me and I got shot down.
-- the field is down! Why did you pork the fuel?
-- Kamikaze heavy buffs
-- They joined the mission, but then went off and..."
-- the two guys pumping rounds into the flaming wreck
-- the conga line wiped out by killshooter
-- or, LOL, what about the "spies?"
Most of these behaviors don't promote the mission objectives, and many may get the pilot a kill but usually an easy death in the process.
Or for pure griefiers, just look at the training arena or some of the H2H discussions. With stuff like the text buffer griefer, you can get someone banned. But what about the guy who just goes down and leaves his escort to jabo a field and die quickly in ack? How do you punish that behavior? Talk about gray areas.
I would hope that accomplishing the mission would be the no. 1 priority. However, survival should be a close no. 2. Self-sacrifice was common in WW2, but usually not intentional in a MA kinda way: "I'll give my life fighting this furball against 10 to 1, so that we can hopefully achieve that war-winning 1-1 kill ratio. In fact, self-sacrifice of that nature was usually rare enough to be rewarded with a CMH or other relatively high decoration.
The guy who chased the FW190 from 25,000 feet to the deck wasn't always regarded as a hero for his dedication, since another 190 or two didn't have to deal with him on the way to the bombers. Particularly if his valuable training and aircraft were lost with little return. The 8th AF only turned back from one maximum effort mission because of opposition (very early on), but numerous fighter sweeps and patrols by pilots in all countries saw discretion as the better part of valor when the odds sucked.
Since beta is at least two weeks away

, why worry too much about it now? I assume thought will go into the point structure to balance aggression and survival issues, and limit excessive training sessions for those who try. If not, then I imagine the arena will fail. I can assume HTC knows this too. Again, though, if you have something better please let us know. I don’t much like the training idea except as a regrettable necessity.
