I'm really liking the idea of Weak Armour. I think it kind of epitimizes the risk/reward. As long as we don't give CAP4 too much bulk then you really have to decide, "Do I risk taking a hit to be faster than this pokemon/this counter?" I think it kind of fits in with the theme of CAP4 being a bug too, most insects have a form of armour, and while durable it kind of is easy to break.
Regenerator just seems too powerful, there's not that much risk involved and it negates our vulnerability to hazards.
I also think that if we decide to go with an ability like Weak Armour or Unburden then our other abilities (if applicable) should also be on the same "good but not uber-good" scale. No point having something like Weak Armour then throwing on Intimidate or something, there shouldn't be a clear winner, ability-wise.
