Is the Lagna Lord's Mahadasha Always Good?
The lagna lord's period is important for everyone and good for no one by default. Dignity and house decide the years.

Important is not beneficial
The lagna lord's mahadasha is the period of the planet that rules the 1st house, so it is personally loud for every lagna. Loud is not the same as good. If the lord is exalted or in its own sign, in a kendra or trikona, the years support the body and the direction. If the lord sits in the 8th or 12th, the same fame of the period is spent on breaks, expense, or withdrawal. If the lord is debilitated, Sun in Libra, Moon in Scorpio, Mars in Cancer, Mercury in Pisces, Jupiter in Capricorn, Venus in Virgo, Saturn in Aries, the 1st-house ruler is weak exactly when life turns toward the self.
The length depends on which planet rules. Venus as lagna lord, Taurus or Libra, lasts 20 years. The Sun as lagna lord, Leo, lasts 6.
Yogakaraka is a different promise
The lagna lord and the yogakaraka are not always the same planet. For Libra, Venus rules the lagna and Saturn is yogakaraka, owning the 4th and the 5th. For Taurus, Venus again rules the lagna and Saturn is yogakaraka, owning the 9th and the 10th. For Cancer, the Moon rules the lagna and Mars is yogakaraka. A Moon mahadasha of 10 years is the self. A Mars mahadasha of 7 years may be the status. Asking the lagna lord to be best for all people skips Mars.
For Sagittarius and Pisces, Jupiter is the lagna lord, and the 16 years are central. They are still only as good as Jupiter's sign.
The Navamsa is the second vote
A lagna lord exalted in the birth chart and fallen in the D9 will disappoint people who expected a universally beneficial dasha. A lagna lord weak in the birth chart and strong in the Navamsa will do more than the first glance allows. Vargottama is the steadier case.
Check the house and the sign before you bless the period. The lagna lord always matters. It benefits the people whose lord can bear the 1st house, and it costs the people whose lord is busy in a dusthana.
