Most games I play end up with at least one unintentional ram, and often ends up with a "ram pile" of three or more ships as the first two ships get in the way of others. I wish there was a better way to resolve the effects of these , but the rules are the best way I've heard of.
Like any game rules in Armada can be twisted outside of their intended use and ramming is twisted this way more than most. The CR-90 + Engine techs ramming machine is the biggest example of this I've heard of. I know another player posted a thread about setting up one of his small ships to be rammed by one of his large ships as a way to keep the big ship on the table.
Both of these leave a bad taste in my mouth, but I haven't heard of any ideas that couldn't be twisted in there own way. Besides the multi-ship pileups, leading to several ships starting right on top of each other the following turn, are kind of fun
