One thing that I do when going into an event is build up my army cheat sheet. I use this in conjunction with the Easy Army list as a basis for a lot of my decisions.
Above is the one I created for my Herd army I used last week. It lists the units I have in the army and for each determines the expected wounds against each Defence level. The two Lycan units could be condensed purely into the second Lycan table in retrospect.
To determine the wounds I have a spreadsheet "Abacus of War" which was built based on the the "Kings of Math" calculator available in the Mantic Forum. My version looks at stand deviations so gives me expected wounds at different confidence levels.
In-game, this means I'm not having it work things out in my head. I can charge my Lycans with Helm of the Ram into De 6 and know I'm expected to do six wounds whereas at De 3, I'll likely do 10. I also know having looked at the stats that I only have about a 5% chance to do more than 8 wounds versus De 6 or more than 12 versus De 3.
That information informs every choice I make. Lycans can't go in frontally unsupported against De 6 and a Beast Pack is unlikely to make much difference. However two Lycans can break it. With a Stampede with Blood of Kittens I can be expected to do 17 wounds regardless of target which will generally be enough.
The ability to make these calls at an instant, increases the speed of your play no end. It has three major effects:
- You have realistic expectation of damage output
- You use less of your own time making decisions; and
- You reduce the opportunity for your opponent to make decisions during your turn thereby pressuring his clock.
The sheet is quick to make and populate - 15-20 minutes - but is probably some of the best preparation you can do pre-battle.
It will pay dividends!
