First things first. I am a public volunteer moderator of the forums on this game. So this review will obviously be biased, but I will attempt to be as fair as possible.
Some background: I am a fan of Sins of a Solar Empire. Once I heard about Sins of a Dark Age, I signed up for the forums. Commander mode came and went, and the beta came out December 2012 or so (around that time.) I was not a big fan of MOBAs at all at the time. I had been a new player and had some terrible experiences with some other games. I sort of shrugged my shoulders and took a hiatus from the genre.
I came back to Soada after 7 months. I had gotten over my beef with other MOBAs and tried it out again. In my second post of Soada's forums, developers personally greeted me and remarked on my feedback. The forum environment was friendly, the game appealing to me, and I was having a blast. I started out just fighting bots. My previous MOBA experience had scarred me against playing against humans. But even against them I was finding myself enjoying the mechanics of the game. I really liked the quest system. It was a neat alternative to the traditional method, and it was sort of a descendant of the Commander Mode.
Eventually Soada came to Steam, and I've been hooked ever since. I started playing against humans, and I even got to play with the developers! It's pretty neat playing with the guys who made Sins of a Solar Empire! (Vasari Loyalists for life!) I am still a fan of League of Legends and Dota 2, but Soada just appeals to me more. I like the dark fantasy setting. I like the mythological creatures and heroes. It is more consistent in tone and theme. The hero design looks grounded in reality and more real than some of its cartoony competitors.
I like the heroes. I think they are cool looking and play great. There are 19 of them at the moment, so it's a lot easier to play them and get a feel for them. League and Dota's rosters can be overwhelming to new players. 100+ heroes and 45 minute matches adds up over time! Quite the commitment! Even though the cast of heroes is smaller, I like them more than some of Soada's competitors. I'd rather have 19 heroes I know and enjoy than be overwhelmed by 100 heroes that I've never played before.
The game has been constantly upgraded these past few months. Character changes, quest updates, new item art, bug fixing, you name it. I feel part of the community. I feel like my feedback is heard, and some of these players are both fantastic teammates and formidable rivals!
Are there any cons? It's a work in progress. Entire systems have been changed in these few months. There was a time where it was more like League of Legends with purchaseable heroes. There was Iron and Crowns, much like Riot Points. It's now truly becoming its own thing. It's technically a MOBA along the vein of League and Dota, but has its own identity. Perhaps "action strategy" may be more fitting since more and more ideas will separate it from the pack and make it truly unique!
I can see this game appealing to fantasy fans. Dragon Age, DnD, etc. The art design, lore, and setting are right up that alley. Table top, pen and paper fans too.
Even hardcore MOBA fans of its competitors might get a kick out of it. I like Dota and LoL, but I don't feel attached to it as much as I do Soada. Would I feel this same way if Ironclad didn't make this game? I don't know. I just know I have a fun time playing it, I feel valued to the community, and it can only get better!
