5.3 = End of the Road for Many (For Now)
To put this in perspective, I've fully explored 5.2 (beaten Collector 6 times), ROL, RTTL, all of it - so had high hopes to beat this content.
Sadly (or happily for veterans, I guess) 5.3 has been designed specifically for long-term players with huge rosters of maxed champs. Due to the insane damage taken while blocking, R4 4*s will not cut it without considerable units spent.
You're therefore looking at needing FIVE 4* R5 (or 5* R3) champs PER CLASS, meaning 30 champs of that level evenly distributed between the 6 classes. This is a benchmark that most players, despite achievements to date, won't be able to manage. I have 9 R5s, 2 in some classes and 1 in others.
Maybe I'll try again when I have 3 of each class, but that's still a long way off considering I'm not in a top 300 alliance (so I have to wait months for T4CCs, or buy them - which I do).
If I'm going to spend the insane amount of units required to complete 5.3, I'd rather just invest in completing LOL easy path instead - the rewards are better anyway.
Some will say I'm complaining, I'm not really, I'm just disappionted that 5.3 has been designed to exclude so many. It was going so well.
