Well i quess the idea behind duel links is games to be fast paced, not like tcg which tend to last forever. Also more lp wont change things since once the field is poped its over. Usually you recieve over 5000dmg. In addition more lp will make cards like cc easier to use. If they have to change something is to limit the number of the special summonings per turn.
The idea of raising LP is to give all tiered decks the chance to get back at the opponent even if you started first or bricked, something that right now is basically impossible, without breaking current decks, which limiting summoning could do. I don't think it's a bad idea though, anything to prevent opponents winning at their first turn when starting second would be good for the game.
Actually from what i have watch, a players turn last forever lol. If you watch a TCG duel you'll miss the old day where " I set a monster, I set a card, I end my turn". Now it's I special summon a monster, I activate this effect, I special summon a monster, I activate this effect, I special summon a monster, I activate this effect, I special summon a monster and it goes on.
