I thought someone could share their luck history or some tips to survive.

However its like every 4th season i face full league of 20% stronger than me opponents. It's like cursed circle:
1th season. You face minimum 15% (often 20% or more) stronger teams in a league and you cant survive - so you cant qualify and automatically became a tank.
2th season. You are god. Or at least you can kick - ass a lot of teams.
3th season. You competing but you end in the middle of table or even can qualify for last spot in champions league
4th season. You face minimum 15% stronger teams and you automatically got destroyed.

Repeat
