I probably wasn't going to take a 2nd witch, unless something happens to the ST4/Blodge/Frenzy lino (he's only 7 SPP from Superstar). Does that seem sensible?
If anything I may take a 2nd runner to get a cheaper MA7 player on the team, and skill him as an initial ball carrier. (If my Guard runner survives he'll be more of a utility runner).
Still undecided though, still new to this elf lark.
You're right the AG5 guy is a lot better than a lino, but he is also twice the TV (140k), and with the 2x +ST, +MA, 2x Guard also on the team we have one of the higher TVs already with only 12 players.
However, I think I agree about keeping him for now, once we have some blodgestep going they will become more awkward to play against and he'll be a bit easier to protect.
