I'm thinking of advocating something like this as house rules (until the Vault rules arrive):
6 SPPs - First skill
16 SPPs - Second skill
31 SPPs - Third skill, Aging +0
51 SPPs - Fourth skill, Aging +1
76 SPPs - Fifth skill, Aging +2
101 SPPs - Sixth skill, Aging +3
126 SPPs - Seventh skill, Aging +4
151 SPPs - Aging +5
...and so on.
No stat may decrease below 1 - reroll any such aging results.Aging Table (D6)
1-3 - Decrease AV by 1
4-6 - Decrease MA by 1
7 - Decrease AG by 1
8+ - Decrease ST by 1
To increase the TR limit, just start the Aging process at the fourth skill instead.
This'd have to be combined with a negative winnings rule or something, to keep the teams that can spread their SPPs around down. A stronger handicap system would also prevent them from getting easy matches just because they have a higher TR.
