On the contrary, I personally don't think he's complex at all. I can probably transform him quicker than Prowl. Kobayshi has a tendency to over-engineer but I think he did good on Ironhide to keep in line with Hasui's design philosophy.
I would say though I don't like how you need to force the side panels to pass a tab on his legs. Kobayashi seems to like to utilize the flex in the plastic rather than friction alone. Tracks backpack basically relies on plastic flexing to hold together and I don't really like that.
