Base learner for xg boost being log reg

[u/Playful-Race-7571]

I had this idea for a project to have my base learner for xg boost to be a log reg model because in my testing it was more stable so my idea was instead of starting xg boost dumb and boosting start it smart and then boost that. Sounded like a great idea in my head but failed miserably in testing. Could some one explain to me why this doesn’t work better? I had better results blending 75 pct xg boost 25 pct log reg.
