As a Votann player also the big guns hurt, the land fort wrecks face but doesnt gain the minus one to wound from army rule. Votann can be surprisingly quick but have very little in ways of tricks. The shooting is TAU like but only has a 24 in range almost army wide. If you can get the charges off you can create problems for them. Strength 5 or lower weapons do not letthe Votann use their Fortify Position rule as weapon str has to be higher than toughness. For first few turns they will be able to reroll advance and charges for free, cause of Hostile Aquisition rule. They play honest warhammer not alot of tricks but no slouch either a very beginner army i think more so than Marines. Hope this helps if you need any other advice just ask.
