Need tips for delve builds.

Basicly im a long time player who is still a big newbie and never went further than the surface of what PoE has to offer.

I was curious what 'strong/meta' builds would come close to builds i like to play, and perhaps you people could suggest me a build or 2? :)

Biggest factor is me pretty much having no currency, so im mostly looking for a build i can start cheap/grow for late game with.

Builds i enjoy/played before:
Totem/ballista builds (Freezing Pulse/Glacial Cascade/Arc/Exposive Arrow)
Cyclone builds (Pyre phys slayer)
Molten Strike jugg
RF jugg
Some necro style builds (played the golem necro/skelemancer when it was strong in Metamorph)

Builds i DIDNT enjoy/played before:
Manabond hierophant (didnt enjoy the mana/dmg phase style)
necro SRS
Anything too squishy

The best one of those you list is probably the RF Jugg because you can be pretty tanky with crap gear.
Then just upgrade as you can.
