First of all, I apologize in advance for my English, as well as the possible lack of knowledge about the mechanics of the game. If I'm wrong, then please correct me.
I. Too compact interface and text / inscriptions. I have normal vision, but to read subtitles (for example) during a match it is necessary to strain my eyesight very much. In just 1 hour of the play session, my eyes are very, very tired. There is images: screen #1 and screen #2.
In my opinion this is very inconvenient.
II. Why is it impossible to rotate the camera like in other games by Relic? I mean the combination "Alt" + "Mouse movement". This would be very convenient and "familiar".
I apologize if this has already been mentioned by someone.
III. I am disappointed that ceased to exist protection system. I'm talking about "green", "yellow" and "red" pictograms, which mark the "protection" of units on the position (like in the previous games by Relic).
IV. Substandard translation of certain names and terms into Russian. For example:
1. "Servitor" is translated as "Ремонтный модуль" ("Repair Module"?!), although in Russian it should look like "Сервитор";
2. "Raven Guard" is translated as "Страж Ворона", although correctly "Гвардия Ворона";
3. "Black Templars" should be called in the Russian version "Черные Храмовники", but NOT "Черные Тамплиеры".
It is possible that you will not agree with me, it is possible that you will want to add something to this list... I just listed the most actual problems FOR ME.
