1. Long loading times. I doubt that buying an SSD will solve the problem. Let's try patch 1.2 and see.
2. The main city image is somewhat lacking, especially after the "wow" effect of the 5th installment.
3. I would like to see a more detailed calculation of damage, preferably in the form of a formula. Some spells seem to show information, but it's not yet clear.
4. Some texts don't fit within the established frames or are hidden by other objects.
5. Random map generator. The developers claimed that it would be easier to build maps, but we'll see. I would like the random map generator to have the option to place random creatures of a certain level with a filter: ranged/non-ranged, for better balance.
6. The most important thing. The AI is slow in battles. It gets distracted by single units, and this has been a problem since the 3rd installment. It needs to be fixed. It seems that in HotS, they wanted to make it so that in a battle against neutrals, the 2nd player would gain control over the neutrals. That would be AMAZING for the 7th installment.
That's all. I repeat, everything can be fixed. Let's see what the patches and expansions bring. Respect to the developers, they're doing a great job!
