Can I get some help with something on Gnar?

So I've been playing Gnar for a while, & love him, but I wanted to try, & make his third hit from w matter so much that Mega Gnar feels like it's in the way. SO! I've tried Ability Power Gnar (Which wasn't as good as I thought it would be) I've tried Attack Speed Gnar, & I actually really like it, except he ends up being terrible early-game, to mid game, & late-game is a monster. I usually start building phage, into Black cleaver first. Someone once told me to build starting with frozen mallet on him which seems to help just as much as cleaver, but with the slow of course. I then snag a dagger for some atk spd, & split between buying my way up to steraks rage, & bezerkers greaves.

eventually I start to slowly become a prob, but it wouldn't bother me so much if I wasn't so isolated from my team. I end up not being able to do as much as I want yet, so farm, & poke when I can. If I fall off for getting impatient, or being too aggressive, then late-game rolls around, & I'm a prob once gain. My build usually looks something like: with a possible substitute for either armor, or speed. My rune page for him is: 1 quint magic pen 2 quint armor 9 marks of atk spd 9 seals of armor 9 glyphs of cooldown reducion

15% atk spd 18 armor 2.0 magic pen (For his third stacks magic damage) 7.50% cooldown reduc

I'm using fervor of battle, & have 12 pts in resolve.

This isn't permanent, but it's what I have so far, & late-game, sure does feel good! Building atk spd like berzerkers first doesn't seem to work, so I get some health, & damage up first, then work on getting it out as fast as possible. With rapid-fire cannon's unique passive, it allows me 35% extra range to auto attack, along with bonus magic damage making my third hits more effective, & easy. I usually purchase cannon for my fifth, or sixth last slot. I'd like some feed-back, pointers on this weird way of building Gnar to be more effective, & less late-game, & more mid game.
