So, the first lord pack is going to be released in late May, and the community thinks it is going to be the HE vs DE one (not exactly sure why). With it, we will be getting Norsca and RoRs.
This is going to have a huge impact in balance.
So, just for pure fun speculation: which factions do you think are going to be the most benefited from this chages?
1. HE. They are a currently a very good faction, with two very obvious weakness (limited infantry choices and lack of ways of killing large monsters).
But they are going to get sisters of Averlorn, a ranged unit with ap, fire and magic damage. That pretty much solves the first problem, and makes the second one much less important.
2. DE: similarly to what happens with HE, they are very likely to seeone of their main weaknesses (cavalry) being covered by the addition of doomfire warlocks: currently, DE have dark riders (good for their price, but unable to pack a punch against anything slightly strong, and the two cold one knights variants, which although decent vs cavalry or monsters, are not viable against anything else due to being slow and having rampage.
However if they get doomfire warlocks, they will get a very fast unit of cavalry (probably as fast as dark riders), with 50% physical resistance, poison and good melee stats. Plus two bound spells, one of them being imho slightly OP as it is to be added as a bound spell (a combination of Morathi, a dark sorceress, and 2 units of doomfire warlocks) will let you drop 4 doombolts at the same time, which pretty much ensures killing the enemy lord.
3. LM (once they get their lord pack):
The addition of ripperdactyls (melee ap flying unit) and razordons (ap missiles on a more or less mobile monster unit with good melee stats) are two very important additions. It will depend however in how they are designed.
