As for the other reasons, there are plenty of decks in Yu-Gi-Oh Master Duel that are incapable of playing through the number of negates and interruptions a Dragon Link deck can put out on turn one
UR Ultra Rare Selene, Queen of the Master Magicians X LIGHT Link 3 [ SpellcasterLinkEffect ] ATK 1850 DEF - 2+ monsters, including a Spellcaster monster If this card is Link Summoned: Place Spell Counters on this card, equal to the number of Spells on the field and in the GYs
Side Deck 15 Kuribah X DARK Level 1 [ Fiend / Effect ] ATK 300 DEF 200 (This card is always treated as a "Kuriboh" card.) When this card, or another "Kuriboh" monster, you control is destroyed by battle: You can Special Summon 1 monster with 300 ATK/200 DEF from your Deck, except "Kuribah"
Even bearing potential link-cable play in mind, this is still a bit of a chore
It shouldn't hurt us that much, but can delay our setup
