So Ziggs is pretty fun

Been having reasonable success lately, wanted to see if I could take him to Rank sometime soon, probably going to want a few tips before trying though. If any of the 2 Ziggs mains out there would like to help, or Mid Lane/Long Range Mage players would like to throw in a few words, they'd be highly appreciated.

Runes and masteries are meh. Meant for my usual line up of AD Bruisers, so ignore the Runes. So far having a lot of success with Stormraider's as it best fits the play style I like with Ziggs, more on that later. My typical build is something like: with the last two items being situational builds. While I say "last two", I'd easily change the build order to meet the situation. In the linked game, I rushed a Banshee's Veil to avoid AP Malphite cheese. I prioritize Mana and CDR to best enable Ziggs' wave clear. Are there any other items I should consider for this build? Or even, should I consider other build paths for other situations? I chose this build path almost strictly for making Ziggs a siege specialist. I was wondering if he can achieve different play styles with other builds.

Laning phase is nothing special. I farm and wave clear from as far away as possible, typically I don't even try to poke the other laner on purpose. Lots of accidentally hitting laners though, entertainingly. I'm rather perceptive with my Ult however. Being a Jungle main for quite a while always as me checking the minimap for opportunities in other lanes. Slightly curious if I'm not taking advantage of some weird and obscure lane advantage trick Ziggs may or may not have. For now though I'm doing a pretty good job at at least staying even in lane, and occasionally even winning lane. My safe play style seems to be doing a good job at not getting me killed. Would also like a general idea of his dumbest match ups and how to build/play around them.

Typically as team fights break out, I look more like a DPS Carry than I do a Burst Carry. To rephrase, I am spamming abilities from as far away as possible to chip at their frontline, rather than diving in headfirst. Stormraiders here does phenomenally well at helping me kite dangers and reposition around my Minefields and Satchel. I'm curious if there's anything in particular to how Ziggs should team fight. It may be because I didn't build for it, but it feels difficult trying to force anything spectacular out of Ziggs fighting in any other way.

Thanks to my build, I've found it extremely easy to just plant myself next to a tower and siege for days, so typically I'm always hovering around the next tower that I think will get contested. It kinda puts Epic Monsters extremely low in my 'order of operations' however, so I feel like I need tips to improve my objective game as a Mid Laner. This statement sounds odd, but the objective game mid feels different than trying to Jungle ( - _ -'). One major fault I noticed is that my deaths tend to occur especially when I'm all by myself. Would just following the team everywhere be enough to help fix my objective prioritization, or is there a more active approach I can take that doesn't lead to a lot of futile deaths?

I think that's it. Any tips and tricks to help improve my Ziggs game would be greatly appreciated.
