I really wanted to talk about the lessons that need to be taken in to avoid some of the major downsides of current gameplay.
The biggest issue, head and shoulders above the rest, is Single Entity spam meta. The meta, both in MP and Campaign play devolves into spam of single entities. I do not think that is something that needs to be proven, watching higher difficulty Campaign videos or competitive multiplayer matches will quite unequivocally show it.
This isn't just about monsters. Single entities, even of small sized are simply superior by design, and the main reason is that they retain 100% of their effectiveness until they are killed or routed. Ranged single entity will fire missiles with 100% effectiveness, melee SE will fight with 100% effectiveness and magic user SE will cast spell with 100% effectiveness until killed or routed.
This leads to a fundamental flaw in the gameplay. Multi model units lose effectiveness as their health drops. So, if one is using multi model units to fight single entities, that person is at a disadvantage from the start. As health of a multi model unit drops, they start shedding models, making them less effective, which is not true for the single entities.
The entire meta currently revolves on pinning and killing single entities in as few decisive engagements as you can manage.
This obviously devolves strategy as most battles turn to disgusting blob fights, where players are forced to try and kill enemy SE as quickly as possible, because if they don't, the investment in that engagement has been mostly wasted.
Healing, while not a decisive part (as even non healing SE are an issue), makes it even more degenerate. Healing in some way, shape or form is available to quite a few factions at this point, and most of them can use it heal their single entities. Even Dark Elves, which don't have lore of life have ways of healing their main SE (Malekith, Morathi), Hydras have regeneration, Lokhir regens in melee and so on. This is not me having a go at Dark Elves balance, it is just to illustrate a point.
Then there is a fact the most spells don't really have any effect on Single Entities. No further proof is needed when Spirit Leech, one of the spells with worst WoM to HP ratio is among the most popular spells, simply because it can damage Single Entities reliably.
This is THE most important aspect of the game that needs to be fixed and I certainly hope we will not see it game 3. Game 1 had a different issue, where SE were too easy
to kill. Hopefully we can strike some sort of balance for the final part of the trilogy.
Some solutions would be:
1) Make SE less effective as they lose health.
2) Make infantry units more effective against them (mostly considering AL infantry vs SEM)
3) For the love of God, do not go out of your way to add more Single Entities to the game (looking at last LM dlc - if there was a faction that didn't need more SE, it was Lizardmen)
4) Make healing less effective on SE.
5) Make SE vulnerable to a wider range of spells.
Same goes for campaign play - SE are even more superior there. They don't lose models, so they just auto heal between battles. Even if they are not at 100% health, they are still 100% effective.
Please, please, please CA, DO NOT allow this to creep its way in the next Warhammer game.
For conclusion, let's have a look at a screenshot from a recent popular youtuber's video of a campaign battle
There's no strategy in this. It is just mindless clicking.
