Well welcome to the community =)
and Kudos for writing a decent-lenght guide.
But there are some suggestions:
#1 Jilly: Its an incredible good starting tower. I go for it 90% of the time. Got good range/speed/dmg for the first 10-20 rounds (since you plan to go shadow anyway and replace it, you dont have to go further with your carry. and 240g for the shadow is normally available on round 5-7)
#2 Your statement about Holgar: "Holgar is so-so". Holgar is the most important tower for long games. You can have it out before round 30 and generate an avarage of 2 pots/rounds. Which gives an INCREDIBLE BOOST to your droprate and all other tower stats.
#3 Electric Chair is underrated. Hits multiple targets. One in range and the first 2 spawned units on the map. Abuse it. (You leak a boss? SUMMON THE NEXT WAVE and your hit will jump and kill the boss over the whole map etc.)
#4 Twisted Mages: They do not suck at all. Just dont go for a single one or his "failing" warp might kill you. Go for 5-10 with speed items and Withered set (Cactus+Toad/Mushroom whatever) and you got an really good chance to kick bosses back to the spawn!
#5 Hitman is far too unreliable with his HUGE dmg range. Beware it got always the chance to deal a single dmg (+pot effects.)
#6 About Shadow: Mention that "Messerschmidts Reaver" is a must have item for him and try to keep his dmg low so he can farm stacks...
#7 Scarface: The "Scarface sucks" is just DUH-UH! Lets face it: Rather low Dmg on single Targets. But with Loads of stuns+possible warps from withered set OR Twisted MAges he can wear down bosses easy while taking out everything else.
Quite good if you intend to skip many waves to stack up the Buzz Buzz Set (dont know its true name ^^)
#8 Honorable mention of : Dried Cactus. Incredible Powerful Item if you play without knux. Loses much of its power if there is a knux around but the only source of "Armor penetration" around.
#9: ALL TOWERS have a Proc-Lock of maximum of 80% proc chance! a Beaver starts with what? 30%? 40?50? Be careful, its useless to buff the luck higher then the 80% proc chance.
Edit: *Beaver got a 20% chance. So a level 10 Beaver with 4 Lucky Pants. got an 37,6% Chance to stun. Sorry somehow i had way higher chance in my mind.
You are right, but I have started replacing hogar with balu, and I found that with the right set up he can outshine hogar, this also depends on what cards you get and when.
Thanks for feedback. I have learned a lot since writing.
I agree that Jilly is an awesome tower. I always used as leak-catcher and never tried her as a main.
I agree that Holgar is awesome...esp on those 500 wave games! What hurt me before was transitioning from a strong shadow which caused a power-loss if I was actually behind. (and shadow was holding me afloat)
Twisted mage strat is interesting. Ill give it a try!
Hitman does suck, but he IS viable. Especially once you get enough attack speed.
Why is reaver good on Shadow? Does each thing he damages proc his adapt chance??
Ill also try out the electic chair. Horrible range but with Jack Ripper that might be a good upgrade path.
