You say that no other hero has two heals from level 1, but you forget Uther :P Everyone forgets Uther nowadays, it seems... :(

The problem with such a build is that, while Fel Flame is amazing DPS, such a build would do nothing to address Gul'dan's main base weakness (that is, lack of burst). I imagine the build would be something like Chaotic Energy, Consume Soul, Hunger for Power, Horrify, Fel Armor/Healthstone, Rampant Hellfire, Haunt. While it does seem nice, Chaotic Energy gives you the same overall benefit as Improved Life Tap, but you lose out on the massive gains from Ruinous Affliction. Whereas if you go...

indeed, though I finished the season at silver 1. I see nothing wrong with someone's rank being "low" if their insights are valid and their tips usable. This guide isn't meant for high-level players who know how to play Gul'dan better than me and are overall better at the game. They already know this. This guide is meant for those players who are looking at Gul'dan as a potential new hero, who, like me, are on the lower end of the MMR spectrum. If this guide helps even one person...

I suppose the main disagreement I see between us is the "random" factor. Where you see skillshots as partially random, I personally see them as mindganes which can go many layers deep. You know the enemy's going to try to dodge, but you don't know if they know you know that, so you aim your skillshot in this manner to see if you guessed how deep it went properly. The same goes with Horrify. A well-placed Horrify can win fights by cirtue of ut being a mini-mosh, and eventually a mosh...

I actually worded it specifically such that it does not deny the enemy team globes. The original draft of the ability had that function, but a friend of mine assured me that the ability to deny globes was way too powerful for a Basic Ability. As for Devouring Swarm, how about if the killed minions grant half or 75% XP? As for the builds, I'll put those up shortly!

The only explanation I can come up with as to why RoD has a higher winrate than Horrify is because everyone and their mother is taking Horrify the majority of the time, though they may be terrible at actually landing it or even playing Gul'dan themselves. They hear that Horrify is the god-ultimate and they use it unconditionally and have terrible accuracy with all of his skillshots (speaking of, Corruption isn't random at all if you're good at aiming it, it's just an awkward skillshot). Those...

It's an acronym for "Public Relations". The overall idea was to have a mechanic baed around Mengsk gaining more resources to work with as he gains public favor by succeeding in the tasks he sets for himself and others

The majority of them may not be major Diablo characters, but I say it doesn't do justice to the other established characters to shoehorn them into Deckard Cain's kit. Personally, I feel as thought it is better to have no skins for a hero than skins that step on the toes of other potential concepts. I don't really have any ideas for a Deckard Cain skin, aside from maybe a Protoss Preserver (they're basically living history books) skin, but that might be a bit of a stretch. Hope this helps!

Please don't have ither major Diablo characters as skins :(

As with my other hero concepts, any talent builds mentioned in the comments will be featured in the concept itself.
