I realize the unlikelihood of major underlying game mechanics like splash attack damage being changed, but I wanted a discussion on it anyway because I really do feel like it is the right direction for this game to go.
As a preface, right now, single entity such as a monster or character or low entity units such as monstrous infantry or monstrous cavalry, have splash attacks. So if the troll does 100 damage and has a splash attack maximum of 4, if there's four targets in range of it's attack animation, it will do 25 damage to each. If there was two it would do 50 damage to each and if there was one it would do 100 damage to each. That is, if they hit.
To determine if an attack hits in TWW2, I believe the formula is (attack stat + 30) - (enemy defense stat) = chance to hit. There's other things to factor in here like charge bonus and unit facing, fatique etc. but the point is that in Warhammer, attacks either hit or they don't.
I think this is actually a bit problem, because when you get into the bigger monsters and strong characters, we're seeing each of their attacks hit for 400-600 damage. With an average attack interval of around 4 seconds, that means that in a span of 20 seconds a single entity with reasonable hitting power can do 2,000 damage... or nothing, depending if they hit or miss all of their attacks. This I think, is far too big of a variance, and also looks bad when a huge monster takes a swing at a hero, sends them flying or knocks them over, and does 0 damage.
My proposed change: Make each splash attack number roll separately, even when hitting a single entity.
So say you have a monster that does 500 damage and has a splash max of 5. Instead of rolling a single hit/miss check when attacking another monster, it would roll 5 hit/miss checks, each for 1/5 it's damage, every time. This would make successive big hits less likely to occur, successive misses less likely to occur, and lower damage but also even it out more across the board. I think this is a good idea to take incentive away from burst damage and alpha strikes and being able to rely on average performance, much like every multiple-entity unit in the game already does, and much like monsters currently already do vs multiple entity units. It's the single entity vs single entity combat that this change would apply to and I think it will help the game to make it less bursty, less streaky, and more in-line with how all other combat in the game works.
