OK here's my take on Wrath of Heroes...
It's exactly as Mythic said: fast, furious and fun. But what they didn't say is it's not aimed at a gamer like me or probably you if you're reading my blog. It's a shallow game that requires no real thought or planning, as there is no real depth or character development in WoH, it's just a drop straight in and play thing with barely anything else to care about. That's not necessarily a bad thing, many folks will see that as a huge benefit, but for me after the initial new toys phase wore off it became a little dull as an overall experience and I have no motivation to log back in. Which meant I just couldn't be arsed with the last few beta events, so I've not tried out the latest heroes and maps added and as such can't pass judgement on those fine details and the current state of balance between the heroes.
The core game itself is just instanced scenarios, which according to Bioware Mythic are "the best bit of WAR", which is obviously complete bollocks as WAR's scenarios are nothing but the standard instanced stuff from PvE MMOs with bolted on PvP. Wrath of Heroes has no relation to WAR's real character and defining feature; open world RvR. So a better statement would be "we took the best bit of WoW".
Harsh? Maybe. True? Definitely.
They have however made the excellent improvement of having 3 teams and that does make for much more dynamic and interesting gameplay, particularly when in a match with multiple premade groups. Apparently this was learnt from DAoC, though really we know this was learnt from WAR and almost everyone that played it over the last few years saying why the hell did you not learn from DAoC? :P
However Warhammer lore fans should note that it is 3 teams and NOT 3 factions, so you will get Chaos, Orcs, Elves and Dwarves all on the same team. A bit shite, but really I don't think they had much choice, as restricting it into proper factions would make it harder to balance and would present problems for a game that requires 3 equalled numbered teams for it to function. Whilst ORvR campaigns work very well with 3 factions of varying population, alas instanced PvP is not very flexible in that regard. So gameplay wins over style, theme and atmosphere. If that's a good or bad thing is totally down to individual preference.
Visually the game looks better than some screenshots suggest and it runs extremely well, though I do think some of the characters are a bit dull and they look like the most basic of their WAR equivalents. That is possibly contributing to the excellent performance, which was impressive and if so is certainly justified.
The heroes only have 5 abilities, which does make gameplay rather shallow, but I think the key here is it's 5 per character and with so many characters to play you can mix it up to keep things fresh. I personally enjoyed playing the Skaven Gutter Runner the most, closely followed by the Black Orc and Marauder.
So we have a fun game, that runs very well, but is just not ticking my boxes. I quite liked it, I just don't care about it. It is NOT an MMO in any way or form and I like MMOs, arena games leave me a little cold. WoH is an ok game and will do reasonably well, but it is not good enough to stop me being disappointed, disenchanted and irritated by the whole situation with this and WAR. If as suggested it will benefit WAR, with more than just jpegs on Facebook teasing people, then I wish it well.
The problem is I just don't believe it will. Mainly because the timing is all off, with 2012 being all about SWTOR, GW2 and even WoW's panda bear bollocks. WoH doesn't compete with those games, but WAR does and I simply can not see how it will find a time slot, let alone the content required, to force itself back in to people's gaming schedules. Unless of course something really drastic happens and unfortunately that is extremely unlikely.
Which I shall say again just doesn't matter for WoH, it's going for a whole other audience and I'm not included.
