Hey, I played the beta on pc to lvl 47 and I played these three characters mainly, Caldarius, Ambra and Ghalt atleast 25 games on each . I also play smite, League of Legends and Over watch.My ign on steam was FightTheTilt.
Through Playing the game intensively mainly incursion mode I realized there are some blatant problems regarding the map and the color schemes, including the highlighting of characters (enemies and allies during combat).
Enviromental Issues:
It took me a while to get into incursion mode, because as I played the characters I felt very overwhelmed and found it hard to focus on characters during the combat especially when playing melee units.
My biggest issue was the map design, there is a problem that involves marquis especially, if left unattended he can snipe from his side of the map to the other side hitting the centry if unattended, and he can take it down.
Oscar Mike’s helix and kit are to powerful, especially his DoTs and his Ultimate, allows him to wave clear, deal damage and siege easily without any pressure. I have lost many games to him because of us losing first sentry and he snipes from the our supply area.You need to re-design those two spots to prevent these cheesy tactics. To much I have felt that the game has not been being played as it was intended because of these two map exploits, unless it was intended to be that way specifically.
Character Balance:
There is one big problem in the game and it is the amount of characters tanks and supports that have hp regen options and the fact that there is nothing to prevent them from healing especially against a team with double support.My worst experience was fighting against galilea , miko and ambra also healing her . It was unbearable. You need to give us options that reduce healing power. It is so bad that it makes playing assassin type characters irrelevant to play , because they don’t do enough damage.
Galilea :
Needs a serious nerf. Her helix is ridiculous when combined with a support and the damage she deals plus her survivability makes no sense. Tanks should not be able to deal that much damage. Tanks , should have high survivabilty and low damage. Other games have this problems, but what is the point of having a front line that cannot be punished for overextending or being overly-aggressive. Please reassess your idea on tanks competitively, look at other mobas and see where they went wrong to help you with balance.
Caldarius:
I think there is an arche-type in the game , which is assasin/skirmisher, I have played him to rank 11 . I have realised his tmp is to weak, and he can’t exactly kill anyone easily. It felt as If I was a like a support. He has good mobility but is damage is really bad and not worth the risk you have to take , with this much healers and tanks in the game. I have felt really behind at many points when I have played him.
Ambra:
Despite her nerf, she was still very strong, because they aren’t abilities /gear directed to dealing with the regen this support gives. She has to much survivabilty because of her fire shield and the fact that she can survive for to long is annoying.
-Make some mechanic available to deal with these high sustain heroes.
Indicators and Mechanics:
There needs to be a way to make communication more fluent. When the game launches, it would be nice to have an indicator that marks the path players are suppose to take etc. I suggest looking at overwatch and smite games for certain ideas like the “v-chat” and stuff like that . Ping commands that highlight objectives and areas.
A system to report and punish toxic players in ranked.
I personally would like an option to switch to third person when playing melee units .
Colorblind Mode Option
A banning system in ranked and also, no mirror mode.
A very good turtorial.
Please revisit the situation with tanks and the amount of damage they can deal plus their ability to survive with sustain
I apologize for any bad grammar, I am not that good . 
Thank you.
