Already looks dated, both the graphics and the gameplay - it's like D3 with everything painted in grey and brown, like it's PS3/X360 era all over again, while the animations and spells are still way off, cartoony, which was IMO the main D3 issue, nothing wrong with vibrant colours if you ask me, if every single area is about to be the same grey and brown then what's the point of having different areas to begin with? People seem to forget how colorful D2 was compared to D1 back in the day, now that was a huuuge change. And those popping up numbers that are more and more common in all the grind-oriented games? Fucking awful, in late-game it looks more like MS Excel rather than actual video game, when did the ordinary HP bar stopped being sufficient.
Not to mention H&S just as RTS is a dying genre, I cannot imagine someone wanting to play this 4-5 years from now...
