The movement 3 hurts. Having to carry 2 subpar models hurts. They’ve not placed in any GC this season. As good as Gurzag is, Skritch is kinda just a better 1 model army and Skaven have the results to back it up. As far as the multiple durable fighters goes, Magore is a better option there. There’s not really a niche for Orruks to slide into right now without them just feeling like you’re playing a worse version of another deck.

As above. It doesn’t feel like a good enough fit to make the list of 10 ploys for orruk. Where I’ve found shardgale good is when you have a lot of aggression to stack the damage after, or with Farstriders where you’re looking to get damage on the way in to bring models into kill range and you really value the chip shots. orruks don’t really want to play either of these ways. They can maybe do it, but then you’re just a worse hyper aggro deck than reavers etc. Play orruks to their strength (trading hits) by running great fortitude to get more health - not shardgale to remove it. You’re a better warband for cards like My Turn than Shardgale.

Most builds have tended to work around that by including Daemonic and Shadeglass Weapons. Given how much better the top 10 ploy choices are than the top 10 upgrades this feels like the better way to fit in cards for dumb and dumber to get involved.

Yes. One of the UK players has been playing aggro Skaven more or less since their release and has good results with it. He also maintains a blog: https://canyourollacrit.com/2018/05/14/grand-clash-round-up-2/#more-359

Unless your objectives have changed a lot - your issue against Scaredy Kat is the low amount of objectives you can get turn 1 and likely turn 2 against the turtle. Realistically scorable turn 1 you have: Brave but Cautious Alone in the Darkness Skirting Danger Farstriders do have tools to play against SC Kat, but you need to keep up in glory. Hold Objective 1-5 are a good shout, or the Supremacy effects can be.
