Personally i would advise against using glory for chests (but that’s completely personal)
I only use glory for buying the new troop each week, and make use of the Arcane Traitstones that come with it to trait other (legendary or higher) troops i already own.
Then again, glory chests have a better drop table then gold keys so it makes them more interesting, but in contradiction to that, a decent/good guild provides a ton of glory keys each week.
Wich brings me to this. Creating a guild for yourself is possible, but perhaps not really as good as it would seem. In relation to my previous statement you can get tons of glory keys from a guild, but that requires the entire guild (wether it be 1 person or 30) to invest several tons of gold into the tasks that give out keys as rewards.
The first priority of gold for any new player should be leveing up all the kingdom to level 10 to get that passive stat bonusses. This can take up quite some time and i believe over a million gold… (NOTE: alot of casual guilds don’t demand gold tribute into tasks if the player in question hasn’t levelled all his kingdoms yet) After that tedious grind, gold is either spent in a guild task or in delves.
To return to the part about guild, the tasks are reset weekly and are therefor very very very tedious to complete when you are a 1-person-guild. It requires insane playtime to collect enough gold for completing all tasks (or even 1 by yourself for that matter).
