Na, Valve is getting the criticism it deserves. When you fuck up, you get called out on it. That's how shit works. HoN was amazing during beta and shortly after release, then it just started going downhill with bug after bug and more focus on cosmetics and the shop than actual gameplay.
Valve is following an eerily similar path... they've done plenty right (TI, esports, free heroes), but they've also been fucking up consistently with critical errors, and going from 2-3 heroes a month to 1 hero every 2 months. Patches seem to have less bug fixes, and with the gigantic list of 1000+ gameplay bugs... it's kind of disheartening. The troll ranged bash bug has been in the game for months, tranquil has been broken by not giving ms to illusions for weeks, armlet bear has been broken for god knows how long, pretty much all of Slark's abilities had a myriad of bugs for months (and still do)... FIX YOUR SHIT VALVE.
