They will implement flying in this game in exactly the same way that they did in D:OS2 - the system is already in the code, and they will simply use it, rather than doing anything better. that means that when you cast Fly, and gain a flying speed - you'll get a new 'fly' button on your hot bar, that will be a movement-based teleport that will see you animate flight from your current location to another grounded location within 60 feet, probably consuming that amount of your movement as it does. This means that when it's not your turn, every grounded, melee character will still be able to run up to you and wail on your or shove you around - you will not be able to actually have or maintain an actual altitude, and it will be ridiculous.
That's basically how Warlock's Imp moves now. Not sure if it's shovable, never seen enemies trying to do it. But yeah, melee range all the way.
Sorry if I'm being cynical; honestly, it's great that there are a lot of people out there who have such confidence in this company. I just can't share it, at the moment.
Definitely can relate to that. I didn't post here as much as others, because my 5e knowledge is mostly Solasta-based, but I read a lot. It's just my disillusionment came a bit earlier. You know, hope for the worst, and you'll never be disappointed.
