tower skilltree third choice and support tower

[Dracov2011]

i have now in tower skill tree archer and fire for more boss timer
and i cant choice my third one, i thinking for poison but not sure, can someone say me wich third tower skilltree is the best one and why ?

how write i choice fist archer, then fire and third poison for dot dmg is this a good idea ?
and support tower:
i have take the 2 chest on up east side and want go west side now for support tower make x5 dmg of hightest tower my mind as extra 4 dmg tower, and after this i want go down for 2 support stacks good idea or bad ?

i think either lightning for more aoe dmg, or energy for more gold drops is better than poison now, i think poison got nerfed a lot?

[Dracov2011]

ok nerfed have read it but i not know this, have start game after is nerfed all
i play poison and have feeling the dot is stronger as lightning but not sure
and energy give more gold how ? see nothing say this no in skilltree of energy tower or general infomration of tower stats :)

Skilltree for energy has an ability that increases gold from supernova kills.
It also has a blackhole ability that pulls all enemies into a neat little stack which makes piercing and it's own explosion AOE much more reliable.

poison away and skill energy is more worth ?

Before you unlock the support tower, I think Energy (pulling in enemies, extra gold), Fire (boss timer increase), and Archer (chance to instantly defeat enemies at low HP) are best.
But after you unlock the support tower, I would replace Archer with Poison.

Reason is the upgrade on support tower which gives you gold for every attack on a treasure chest. More poison ticks = more gold. It's too broken to the extent I think it might get a balance patch.

*Edit* I should mention this assumes you have enough ether to unlock a lot of the skill tree to reach the unique skills of some of the towers. Otherwise just use anything you like until you have more ether.
