Multi-ticketed nodes do nothing good for the security / decentralization of the coin, quite contrary. It's just there to make whales earn money even easier.
Actually one good thing is that bigger payout to multi-ticketed node allows the node to be hosted on a higher priced quality server. No idea how many would do so though. But simply having someone pay $10 a month or w/e for vps and run single node with 150 tickets that does the same amount of work than a node with 1 ticket just doesn't seem good.
