Changing openings for extremely long term improvement.

@Chambaru first off, not cool to use some alt account and point to a bio that doesn't exist. But if you want proper advice, look at Silman's famed "How to Reassess your Chess" at page 391f.

Citing the core point:
"if you are more interested in improving your overall understanding (rather than just gaining a few rating points due to the help of a complementary opening repertoire), then a very different opening philosophy can be implemented:
Choose openings that don 't suit your style/temperament!
Choose openings that cater to your chess weaknesses!
Choose openings that freak you out and leave you feeling vulnerable and insecure!

In other words, this system of thought recommends openings that force you
to come face to face with your chess failings so you can patch them up! [...] Be warned: This "bizarro" repertoire is only for brave souls who are extremely dedicated to improving every facet of their game, no matter how much pain and humiliation it takes for them to achieve it (and there will be pain and humiliation since you'll suffer many losses as you slowly but surely raise the level of your chess IQ)."

You don't need to change your opening since you improve you knowledge in it

"... It is illogical for one who has not earned his master title to ape the complicated opening variations played by, say, a world champion. After all, while the opening is indeed important in chess, it is still only one part of the game; victory can be found as well in the middlegame or endgame. Your only task in the opening is to reach a playable middlegame. ... How should we lay the foundations of our opening repertoire? It is hard to come up with a single answer to satisfy every player. Individuals will have different objectives in the opening, as well as different playing strengths. Nevertheless, to all players I can recommend the following: simplicity and economy. These are the characteristics of the opening systems of many great masters. They do not strain unduly for advantages in the opening; they would just as soon move on to the next phase of the game, hoping their skill will overcome the opponent in the middlegame or endgame. ... the most complicated variations demand huge amounts of time for home analysis, time available only to professional chess players. ... I will discuss here only openings and defenses that in my opinion offer simplicity and economy. ... The Dragon and Najdorf Variations ... have been analyzed to twenty moves and more; if a player without adequate preparation walks into an analyzed sequence he may lose even to a weaker opponent. Under no circumstances should you handle these variations in serious games unless you are a professional chess player with unlimited time for study. ..." - GM Lajos Portisch (1974)
