I disagree with RL 100%, we raided and took a harry (probably that harry) in hyloth from heat on atl. Hell hounds were everywhere (i assume heat made them). We made a push and dropped heat. The hell hounds were annoying, but really you can deal with them, we did. I do admit that the hell hounds proved to be bad for the other people who tried to push us later. However, if they didn't run so much (and played a mage template) it wouldn't have been a problem for them either.
Hell hounds are great. It pushes people out of despise and into other areas to spawn... I think that is great. Baracoon should be a harder spawn and thanks to EA it can be now.
Hell hounds are just a tactic now. Not much different than a harbringer (although there are only so many harbringers, but they can be made anywhere).
Please keep helhounds in play. I don't use them, but I like options in the game. I think it is great!
