Welfare epics describe the arena epics you can purchase. They are called welfare epics because of the presumed ease at which you can obtain them.
The biggest complaint is the fact that you only have to participate in, not win, the arenas matches to earn points. You can essentially have a losing season and still come away with rewards.
Of course, you gain less points this way and players tend to gloss over how long it takes with the 10 games a week method.
Players also complained about the Headless Horseman helm and epic rings. The helm may have been on the level of tier 4 or better and the rings were exactly like the ones you can buy with heroic badges.
As a result, these higher rated pvp teams and players who had ran heroics over and over felt their efforts were diminished.
Blizzard is changing the arena awarding system with patch 2.3, but there are no plans to change the HH event to make it harder or remove the epic drops.
To those who think casual, not-so-skilled, or whatever category these welfare epics are ascribed to shouldn't have a chance at what some take for granted I say this:
This is a carrot-chasing game. We keep the cart moving by trying to bit at the carrot. For some of us it takes weeks, others months. Why one donkey cares what the other donkey is doing I'll never know. But to stay in business they have to let us nibble on the carrot sometimes lest we lose sight of why we're playing and get a taste for apples.
