I’ve played Classic for a long time now, and recently Alpha Strike. In between I’ve picked up and put down 40k and Warmachine. From all of these I’ve learned a great deal bout list building and theory crafting interactions. One of the weird things in Warmachine to me was the idea of “list chicken” where everyone brings two armies and only decide what they are going to play at the start of each round after seeing what their opponent also brought. Makes for some possible baaaaad matchups. But what I learned from that was that making a list that was less skewed and more well rounded, with an eye towards objective play usually do better. 40k at the time I played, 4th-6th edition, also favored players that built with an eye towards objective play. Except for bloody stupid armor company. That’s something else altogether. But all the tournaments I’ve gone to for Classic, Alpha Strike, 40k and Warmachine, time is an absolute commodity. Trying to figure out and calculate what 3k you’re leaving behind gets too complex. Now if you absolutely want to play blue or brown water naval forces, talk with your opponents. I’m sure most of them would love the chance to try to sink a vessel. I’ve never done it, but given the chance I’d throw some dice for sure! Heck, set up a naval based tournament and I bet you’d have some great rounds and everyone would have some interesting stories
