I factored in everything; quest rewards, chests, drops.
When I tested it on my GM, I got 9.3k.. on 2x
Even when I did it as a player, I got upwards of 6k. ._.
Full BR, never learned to PVE.
To correct this, when u are soloing or duoing you can only really do all 9 once a week, as the second time the mobs and bosses has 50% more hp, making trial 7 almost impossible.
And I think most casuals doesn't have enough time to do more than 1 a week anyway, tho if you do its best if you just make another guild, I myself have 3 factions with bases.
Some people no-life farm all 3 rounds, I know several people who have more alts just for trials, as it's fairly easy to level seekers, but you're right. For normal people who don't want to farm 24/7, one round is most likely.
