There's an extreme disparity in map awareness and experience. I feel like the game would be better if everyone has a similar base level of understanding. This could help achieve that and defuse perceived tensions between casual players and those seen as elitist. The hope is that most future suggestions will be based off of comprehension. That people can try things in a setting where they don't have to perform or manage the objective. They can grow, if they wish it, at the rate they are most comfortable. From that growth they will be better equipped to affect the outcome of what they choose to participate in. Perhaps enjoy the Crucible more.

Something that came to mind as I was reading your post was the idea of a place where a player could practice the 'flow' and timing of a build to get the most out of a rotating playstyle, such as (totally random) using a melee to proc a grenade leading to.....etcetera. Definitely a suggestion with merit and something I think a lot of players could make use of.

For sure. I genuinely believe it could help all interested parties at any and every level.
