I think one of Albion's biggest problems, is the amount of obscure mechanics, and lack of tutorials/guides. Wiki is completely outdated, guilds hoard their knowledge, and even among the top end players, a lot of them still don't know how some basic mechanics work. I recently made a test and asked some veteran ZvZ players, do they know what resilience penetration stat means, and majority had 0 f**king idea, they thought it's about penetrating armor, because it's not explained anywhere in the game.
Majority of people in alliances like ARCH, probably don't even know that something like AoE Escalation or Focus Fire Protection exist. They don't know how debuff works. They join some big alliance, go to zvz, get oneshotted, and have 0 idea why enemy 100-0 them in 2 hits, while their E's hit for 100 dmg, and they feel overwhelmed. For many players, even if dying isn't a problem, lack of ability to understand WHY they died and learn from their mistakes, certainly might be.
I recently got asked by a player in my guild, how much siphoned energy is generated by our terries, and I realized that I have 0 f**king idea if it even still generates energy at all. Out of curiosity, I went to wiki/forum to look for answer, and I couldn't find any. You can't learn how launches on terries or hideouts work, from inside the game. I've met GMs of mid-low level ZvZ guilds who had serious misconceptions about some of the launch mechanics, after years of playing. You don't know why you get a random debuff to fame when you're in a big alliance with a lot of terries. You don't know why your guild gets a seemingly random number of season points stolen by the alliance, and what categories can it steal those points from, unless you read through 50 patches to piece together that info.
Over the years of playing the game, I met shitloads of players, who simply felt like they couldn't really progress and catch up, unless they were willing to slave for a top-end guild for months, to be able to learn how the game actually works. Barrier of entry is incredibly high, and that's just for understanding basic end-game mechanics. Learning how to actually play zvz well, is entirely another thing. In some zvz content like castles, even majority of older "zvz guilds" act like headless chickens and have absolutely no idea how to properly play them. And don't even get me started on crystal league, where there is like 100 guys in the entire game who are good at it, and season winners are in 90% decided by this most obscure content in the game.
I think right now, if we had some guild migrate to Albion from some other game, bring in 200 fresh players and try to build their own thing here, no matter how much they try, they'll probably never catch up enough to be remotely competitive with even the low-end existing blackzone guilds, unless they're willing to slave for someone first. Knowledge simply isn't available, no matter how much they want to learn.
Albion could really use far better tooltips, and some in-game codex that would explain all the obscure mechanics in-depth. Even more, it could use more content creators willing to share their knowledge, and help new players and fresh guilds progress and catch up.
It's not a problem that's easy to solve, because obviously guilds have good reasons to guard their knowledge, it's one of their biggest assets and by giving it up freely, they would shoot themselves in the knee. But at the same time, lack of learning resources does discourage many people from playing, even ones coming from "hardcore" games, which isn't good for anybody. Maybe SBI actually hiring some veterans to act as content creators and prepare tutorials, would be a way to go here?
