Hello. The main reason why I was drawn to Warmahordes almost immediately (over 40k) was because I noticed that my success in games was almost completely based on how I played and not on what faction or list I had. I played 40k for about 2 years (and I don't know if this has changed in 6th edition), but generally it came down to list vs list completely independent of how I played. When I picked up Hordes, I was pretty happy to find that I could show up to a game night with one set of models and play against anyone and still have a chance in hell.
-While I agree that you are more sensitive to dice rolls because of the pitiful amount of rolling involved compared to 40k, you have options like boosting and rerolls that allow you to increase your odds or dice reliability. To say that the game has no tactics is completely incorrect, it actually has too much tactics at times. A lot of my favorite strategies involve placing, locking, and moving enemy models; this is very rare in 40k, but adds a lot of strategy on the board
-If you are playing a shooty army range should not be an issue, when you have guns with 16" or 14" range there are very few models that can make a charge at that range. The problem is that you get a very small margin of error in trying to guess distances. Trust me though, armies and lists that were meant for shooting have no problem with range.
-I forget who said it, but it explains the mechanics between warmachine and hordes simply, "the focus mechanic is about resource management and the fury mechanic is about risk management." I rarely go "balls deep"
because I know my list cannot handle that type of playstyle.
-Feats were designed to be game changers. Some are extremely powerful, but usually you just have to know what they do to find ways around them.
-It's probably the first lesson everyone learns, protect your warlock or warcaster. Also, I don't think it's fun when players feed me their warlock or warcaster.
With all of that said, I think the biggest drawbacks to warmachine and hordes are: hobby aspect (no extra bits), factions have predefined "battle strategies" so you have to make the choice between what you think looks cool and what actually fits your playstyle, and getting sucker punched by some crazy combo you never saw coming
