Sorry I'm just gonna break the format here to explain one of my thoughts in a little depth. Apologies If this isn't the place for this.
I actually really enjoy maps where long games are possible, and honestly I feel like a few maps have serious flaws in terms of egg positioning to the detriment of that, especially when going against a team competitively.
Take space for example, I really enjoy the fact that you have another option when It comes to diamonds and it makes it harder to deny dia. altogether from a team. If they decide to buckle down and stay on base to defend their egg, There are always multiple options when It comes to attacking (mid, planet or the tips of either neighboring bases.
However, As I mentioned previously, It's the egg position that just isn't on point, It's in a situation where if you're up against a team who knows what they're doing, It's Impossible to get it when alone. (speaking from a mostly normal and not OP perspective here, but in hardcore it's even more egregious). The problem being that the time it take to break the egg with an efficiency 3 pick on a dual or even single layered egg is shorter then the time it takes for them to respawn, and walk over to the egg, this is combo'ed with the fact that the team is four players large, you'd have a hard time even covering yourself in blocks with how they would overwhelm you (with spawn protection, at that!). A simple solution to this is to make sure the egg is far enough from spawn where this isn't a factor, somewhere say, on top of the ship for example, this would also have repercussions for early game rushing though, as they would most likely have to climb to it to reach when going from mid.
Maybe I'm just salty because it happened to me more then once lol, but Anyways, as for my favorite maps, I'd have to chose:
Favorites:
Teaparty: 5 Player teams and an incredibly large maps make most of the games long, recently this is becoming less and less fun for me, with the advent of the blunder of a game mode called OP. Finding people who know how to play will assure that the game will never end with how easy it is to get diamonds and how little void drops there are. I hope you enjoy spamming people in diamond armor on the clouds... Because that's what you're going to be doing;
Forest: Small distance between mid and other islands make for usually a pretty straightforward game. The late game is all about stealth!
UnderTheSea: You'll be hard-pressed to find an UnderTheSea where people don't camp at base, and that's precisely why I love it, It can be infuriating at times, but sieges are a lot of fun to do on these maps and very satisfying when you pull them off :)
Least Favorites:
Pizza: I wish the distance between twin islands were larger, It always ends up in being a very early one sided rush, though It does have potential, I really like the concept that at the start 8 teams start and only 4 teams get to continue to play early game.
Magic: oh lord magic desperately needs an overhaul, the games end up being so short due to the lack of diamond and gold on 4 player teams, we probably all know about the dia gen on the wizard's head already, but chances are your egg will be broken by the time you actually reach it.
