Right now my mech bay is all assault mechs. Because there is no reason to ever have a light or medium mech once you have better mech. Introduce missions with preset drop weights! It would give us a reason to keep lights/mediums
No, no, no! No preset drop weights! Anybody who has a hangar full of decked-out assaults earned them and deserves to use them. Besides, limiting drop weights is an artificial constraint.
What we need is a REASON to CHOOSE lighter mechs over heavier ones. That reason can really only come from an expansion of the (nearly non-existent) strategic layer of the game. We need bigger, more complex contracts with interlocking missions.
For example, give us a contract to destroy a valuable and extremely heavily guarded factory. Then give us some options.
Let us deploy a scout lance to recon the region around the target. Make it the same kind of thing as infiltration in XCom 2 - we drop the lance and wait 3 days to 2 weeks to see what turns up. Make the outcome dependent on several factors:
- Speed and maneuverability of the mechs assigned (fast is better, slow sees nothing then gets ambushed and surrounded)
- Skill of the pilots (Piloting and Tactics are best)
- Time spent scouting (more is better, but too much gets you ambushed)
Make it so that a light recon lance will probably get good Intel and maybe a shot at a target of opportunity, and a slow, ponderous lance will most likely get ambushed by a battalion of tanks. That's a great reason to keep some fast lights, no?
Once the recon is done, depending on how well it went, more missions could open up. Maybe there's a fast, lightly armed convoy to kill in order to force the defenders to move some troops away from the factory. Good job for some 5/8/5 mediums, no? Maybe a raid mission, where the target isn't so we'll defended, but lots of defenders will converge as soon as the attack begins. Another good use for mediums and heavies, since assaults are too slow to withdraw. The AI could use lots of tanks and LRM carriers to ensure that the player gets the message that sometimes speed is best.
Once the defenders have been harried and drawn away you can take on the final mission and drop your assaults to crush the guards and level the factory. If you did enough prep work then you'll have a fierce, but completely winnable fight. If you half-assed it you get sandwiched between 2 battalions of Demolishers and have to run away.
Please developers (or more likely modders), make this happen. Give us a robust, challenging strategic layer that rewards us for keeping our barracks and hangars filled with a variety of pilots and mechs. Give us the chance to actually command a company of mercs with a complex task to accomplish.
At the moment we're just heavily armed day laborers.
