I'm being dead serious here. When I play a DPS character I'm generally trapped with three options:
1, if I'm deciding to do what EVERY DPS character and their dogs do, I buy Berzerker greaves.
2, If veigar is pissing me off, I'll get merc treads.
3, by some weird point where another DPS character is tearing my face off, I'll buy Ninja Tabai.
Now, the issue with this, is that berzerker greaves don't really scale well. It's what most DPS characters use, but there's not really an enticement to wear them when 2 phantom dancers (items that are not uncommon for DPS builds) offer you MORE than berzerker greaves in every aspect.
Meanwhile, mages and tanks both have boots that are good all day. The ionian boots and Sorc Treads make life easier for mages, and Boots of swiftness, Ninja tabai, and Merc treads are all available for tanks.
I feel like the DPS crowd (not that we aren't OP as can be the way it is), need more appealing boots.
My suggestion? A pair of vampire boots, and a pair of crit boots.
I think I'd find myself wearing more boots if it gave me vampirism. Vampirism items are generally a bother to have in my inventory because they're relatively required for DPS champs, but really ONLY offer you that vampirism. Buying one clogs the inventory and makes it impossible to buy items like black cleaver without sacrificing something in return.
The crit boots just feel good. I probably wouldn't wear them till late game (once again, phantom dancers), but they'd give me a little buffer room as I build a crit chance.
I know this will get yelled at, but it's an idea.
