I hope in 2019 we can expect a good deal of content for non beginner, non end-game players. BECAUSE
There's a good chunk of players who have a decent roster and decent fighting skills but still aren't able to beat the latest end-game content additions. And we're stuck waiting for the next monthly event to do something new.
I, for one, don't ever imagine beating even the "easy path" of LOL. As it stands, I have not been able to explore 100% the last three Uncollected monthly events because the final boss (or second to the final boss) were just beyond my fighting ability and would require a hefty amount of units to win.
I hope the game development team of Kabam will reconsider its efforts to prioritising strictly beginner and end game content. I honestly both beginner's and end-game players will never see contentment to their plight of things being too hard (beginner) or too easy (end-game) but what about the rest of us who find beginner content too easy and end game content too difficult?
The rewards, of course, should be scaled to accommodate between mid-game to end-game difficulty. I'm not expecting the same rewards given to end game players but should be enough to make it worthwhile.
