I am happy that many of you have noted that the Hoplite is better at maintaining a volume of fire, while both mechs lack a volume of firepower. They sacrifice defensive the weaponry that makes heavies all so terrifying. As players have noted, the mechs do this to different ends. The Hoplite maintains the primary firepower of a heavy (Think an Orion), with the inability to add the defensive firepower that makes many heavies so formidable at closer ranges. One iconic feature of heavier designs in tech 1, is often the firepower of the lighter design, with the heat sinks to indulge. The Hoplite is a team player. Its armor is at a fair level for some heavies. In contrast, Griffin uses mobility to cause problems, but that same mobility forces players to learn to ride the heat scale (Not a bad thing). Griffins do often end up in static positions due to tactical considerations, and that mech's fair armor. They are also sometimes used to cover retreats (They can get there, but lack the firepower to turn a situation around. They may dissuade some mechs from acting on the circumstance, like a Commando). When used correctly, both mechs are quite handy.
An important difference is that the Hoplite is far more likely to force at least 20 points of damage. It will also end up in the open in games, because momentum will become key. Whether that is the right choice, or not is contextual. If a player has a chance to gain momentum, they have to weigh it against their tempo. Players also sometimes forget that a Hoplite can kick, or charge, just like I have seen armless Griffins turn to brawling. Part of seeing the whole map is knowing what any given piece is capable of.
Knowing how a mech can work is foundational to force building, but so is experimentation in units. What types of units would you deploy a Hoplite with in a force? How about a Griffin? Terms like Sniper, Skirmisher, ad hoc Skirmisher, and Missile boat have their limitations. I do not tend to use these terms, with the exceptions of skirmisher (Due to historic context) and Missile boat. I noticed one player designed a force for a lance on lance game. How would this differ for a company force? Why do you use that lance design?
