Warranties are for manufacturing defects from the company. Damage you cause by using them is not grounds for getting a new free pair of skis. I don't get new skis every time I get a core shot from skiing in the trees. While you may get lucky with companies like armada and line, its very rare that you'll get them replaced because of accidental damage. Skis aren't indestructible and impacts with hard objects cause damage, its reality.
This is getting to be a horrible trend in the industry, just like suing a mountain, take some responsibility for your own gear.
