The current model of units beeing able to capture vast amounts of planets is wrong, in my view. There will be always factions with less population than others and that leads to absurd results as seen in the current map. It doesn't help creating good matches and it feels very wrong seeing half of the innersphere beeing captured by any faction in only months.
My proposal:
Create hot zones along the borders between IS / Clan, IS / IS, Clan / Clan.
One permanent hot zone between IS and Clan, consisting of some planets (like 3,4 idk), is designated for constant struggle. Make capturing a planet a long campaign and winning a sector of a planet the equivalent of capturing a planet as it is now. Sectors wouldn't reset for ceasefire, but had to be reconquered.
Different "hot zones" can be established for a limited amount of time (eg Davion attacking Kurita or whatever), in which one faction (could be even coalitions (Davion-Steiner vs rest, wardens vs crusaders) is enabled to win a planet from another and is given like 3 days. This way there is constant possibility to play in the main "zone" for Pugs and groups alike, no mather the faction (IS / clan) and at the same time faction only operations along the small campaigns.
We need less planets to fight on, where more action packs and more meaning is given to.
Considering maps/planets:
We'll never have appropriate maps for all the planets and thus it soon feels dull dropping on the same planet in all the different maps. Which planet could look like this? Sorry to point this out again, but immersion is the thing we need more of.
Instead:
We need a spaceport map. I don't care to fight on the same map on all planets, if I'm able to make smth up about it in my mind. There are spaceports on most planets and most could look similar. It would always be the first sector to conquer on a planet and only if its fully captured, there can be skirmishes on the other maps we have. Add 3-4 of the existing maps to any "hot planet" and choose them that way, that they match (geological wise).
If a new map is made, say the spaceport, create 3 different versions of it. Fresh, damaged, almost destroyed. That would be less work than create 3 entirely new maps and adds a hell lot of right feelings to it. Which one would show up, would be determined by the amount of sectors conquered.
While you're on it make an industrial complex and a fortress too, please

My general aim is to concentrate the action in a smaller area with more incentive to play. Immersion is everything in CW and with just small actions you could make us the players dive into it willingly.
On a broader view:
Just an idea for the incomes of a unit. Every player should be able to create several dropdecks. Those mechs in the decks should be mirrored for CW, meaning you can play them in CW and still in the regular queue. Dropdecks should be prone to rearm & resupply, meaning you can't redrop with a single deck till its fully restored. Based on your performance, you'll gain x salvage points, which are used to repair your deck. If you do good enough, you'll be fine. If some amount is missing to fully restore your deck, you can pay it yourself or your unit. Thus a unit could use its coffers to quickly restore its decks. On a sidenote, maybe the repair could be linked to certain amount of time and the instant repair option only available to units.
Trial mechs would not have a need for resupply, making it new player friendly.
You can still drop in your other deck(s) - hopefully we'll see more different mechs then.
Would appreciate any feedback, cheers.
