I don't know... I suspect you might hear more ragging than usual - about all the noobs pick-augering from their Temps and 262's. Speed might not help anyone's gunnery or flying, but it sure can put 'em in your face quickly. The first of each month would be sort of like jailbreak day.
For once, I would love to encounter a noob in a Tempest. haven't killed one in almost 2 years now and want that "kill every plane" achievement.
Can't say that I'm in favor of a monthly handout. An alternative would be a one-time handout to new customers after 30 days of playing. HTC could deter shades capitalizing by keeping track of ISPs, which they probably do anyway. A recurring handout is not a good idea, IMO. Just like the skill to fight has to be gained through fighting, so too should the perks.
