So – my Skaven team has been smashed to smithereens (three dead, two injuries that require sacking

) the first two matches (1 lost, 1 won), but after match two I had my first skill-up on a GR – and a double skill-up, even – which resulted in +AG and Block.
Now, after match three (another victory and this time no dead players or even injuries!) I have four more skill-ups to decide. One was a double 6 on a GR

, so I’m not going to need help on deciding that, but the other three are up for discussion. I’m especially interested in hearing peoples’ thoughts on the GR that rolled a double and please consider the two GRs that already skilled up.
As written, I have played three matches and it’s an eight (nine or ten if you get to play-offs) match league with possibility of keeping the team for a subsequent league.
Here’s my current roster. All help and words of wisdom very appreciated!
- Thrower: ?(standard)
- Blitzer: ?(standard)
- Blitzer
- Gutter Runner
- Gutter Runner: +1 Ag, Block
- Gutter Runner: ?(double)
- Gutter Runner: +1 St
- Lineman
- Lineman
- Lineman (Journey)
- Lineman (Journey)
(Oh, and the opponents are: Underworld, Human, High Elf, and Nurgle. I'm playing everyone twice and have played the first three once already.)
