I guess first I'll start with Mech diversity. Without a premade you don't get Min-Maxing on the team level, so people take Mechs that they do well in solo. Now the Clans don't really see the diversity that the IS sees since the StormCrow is so ideal, and there being far fewer Mechs to pick from on their side, but thats a different issue.
Second is tied to the first. Because of independent Mech selections, you don't get "Wave Play" as much. A premade can set up each drop and "rush" with that type of Mech, whether a Light Rush or a Crab "Rush". The team goes in together, kills/destroys objectives that they can, dies together, and then spawns together. This type of play is too COD for me, encouraging the rush in kill die respawn mentality. Its hard to believe you are a Pilot of a Mech, when you throw away your equipment and life so easily.
Times to find matches of course is nice. Which do you ride, the best Rollercoaster once or the second best 5 times in the same wait time? Which do you remember being more fun?
VOIP, not really a challenge specific thing, but it made CW much better with PUGs. I really like the push to talk aspect and the lower quality of the voice (oddly), it really makes me feel like I'm talking to Mech Pilots on the field.
In the end, the conclusion I feel I've come upon is pre made teams are overpowered. I know this has been joked about, Team work is OP, but this isn't about just working together, its about building a teams drop deck, and coordinating the plans before the battle has even begun. Now I love strategy, so I would think I would love this, but I just don't think the game handles the balancing very well, making it not as fun as it should be, hence why its more fun to drop PUG vs PUG, or at least small groups vs small groups.

Quick ideas of improvement/change (just throwing ideas out here).
A matchmaker for CW that puts teams of the same size together, lacking that, it grabs the highest ELO solos/smaller teams to challenge the bigger teams.
Pay a price for death and a little less for just a loss of a Mech (Ejection). Not sure how this would be implemented, maybe just C-Bills maybe Honor with your faction.
More Mechs per drop with less drops per player. I'm sure this is a technical issue, but if you had more simultaneous players say 16 on each side, but 3 drops that would encourage you to stay alive a little more, also maybe only one large group per team, so still a max of a 12 man, or even limit it to 8 man max (I know you'll hate that idea
