Effect of base conc. in weak acid/strong base titration?

What exactly is the effect on the equivalence point pH when the concentration of the strong base is changed.

I know that increasing the conc. of the strong base decreases the amount (mL) needed. But does it change the eq. pt pH? Thanks

Equivalent point shouldn't change as acid and base equivalents matter.

Although, I have noticed that the change in pH around the equivalent point is higher at high concentration. What I mean is with low concentration, the straight line is short; while in high concentration, the straight line is long. However, both have their equivalent points same.
