Well I tried with that synergy part. The fact that they have a lot of synergy does not mean they are stronger since it's taken into account when the base stats are balanced. For example berserker has much more hp/gold compared to nightmare bc of the butcher heal and so on. When it comes to AOE vs single target I think AOE can be very powerful, it can save you a lot of attacks by your dps fighters. For example, honeyflower hurting the entire wave can make wileshroom save 1 attack per creep and thus you get rid of the waves dps faster than you would with only single target. You can also avoid leaving units with very low hp that just survives forever and destroy you just because they don't get targeted and so on. AOE is obviously not always better, bad against bosses for example. But a race having no AOE at all is a weakness, not a strength. Lod is widely considered the least useful and by many also the weakest t6 and it's a real problem you don't really want any until 19/20 and then suddenly you want a lot of them but simply don't have enough gold.
