Extremelly unobjective and innacurate analysis. If Djokovic "solve" Nadal in 2012... Why did Nadal dominate Djokovic in Grand Slams in 2012-2014? Nadal beat Djokovic in 4 Grand Slam matches in a row between 2012 and 2014, including a match at the US Open. And at Wimbledon 2018, Djokovic almost lost to Nadal on indoor grass. So it is far from objective to say that Djokovic has "solved" Nadal in 2012.
Second, since 2008 Nadal is 6-1 against Federer in Grand Slams. Federer has only beaten Nadal in one Grand Slam match in the last decade (AO 2017). Only 1 victory of the last 7 matches in Grand Slams is not enough to confidently state that Federer now has "solved" Nadal. Also, your assertion that Federer has "solved" Nadal since 2015 is completely misleading. They only played 1 match in 2015, 0 matches in 2016, 4 matches in 2017, and 0 matches in 2018. So in reality, Federer has confortable beaten Nadal just one year (2017) in his entire career. The sample size is too little. Just because Federer has confortable beaten Nadal one year in his entire career, it is not enough to say that he has "solved" him.
The solving thing makes me laugh.
Djokovic didn't solve Nadal, he always had the edge on HC anyway, on clay he gave him a few close matches but was clearly second best. In 2011 what happened was he became a better player with more confidence all round - vs everybody. He beat Nadal in IW and Miami, but he'd done that before and the 2011 matches were actually tougher than most of his wins over Nadal on HC, Nadal was playing some top tennis at the time (I think at this time Djokovic led 7-5 on HC, 7-4 in best of 3, so these wins were nothing new) on clay he beat him for the first time but I believe this was because he got in Nadal's head and not because he altered something about his game to solve Nadal. What then followed were periods in which Nadal was mentally better and periods where Djokovic was. It wasn't like Djokovic couldn't beat Nadal before 2011 and Nadal didn't win after this. Their rivalry has been extremely close.
With Federer I do feel he solved Nadal, in that he altered his game (more specifically his backhand) and had a different mental approach to turn things around. However, this doesn't mean Nadal can't now solve Federer's new game and turn it back around. That's what people don't get, the game constantly evolves - even for the oldies lol.
