Often time the ability that scales best and focuses on DPS is what gets maxed last as only by that point will you get enough AP to really make it matter, whereas early game you're often better off with the bursty abilities that relies more on base than scaling.
However, Heimerdinger is...unique. Unique in that he does literally everything with his turrets. Should he level up his rockets first or should he level his signature turrets first?
assassin donger: missles troll donger: turrets jungler camp me pls donger: grenade
All depends on you and what you're facing.
If you're vs someone who can easily take your turrets out, rockets may be better as first, or wave the two. You don't have race to max one first.
Get your turrets to where you're happy with them then get your rockets is generally the best setup. If you're feeling OK at rank 3, Stop at rank 3. You can hold 2 charges at that point and the turrets scaling is also factored to your level.
I always max turrets first and rockets second.
ALWAYS
Plz dont play the donger
I only play the donger in top lane vs auto attack reliant Champs. Turrets every time.
The turrets are your main source of deterrence and farm. It's what makes you undiveable. You don't have to max them, you just give up a shit ton of security.
I actually don't have anything to contribute to this discussion but, OP do you play capoeira?
Maxing out his turrets first has always worked best for me. Provides great farm and protection during the laning phase. I max out rockets seconds, but it's all up to your play style.
