Help with a new army 2k

[allmyhormieshatesm]

Hey, just got into 40k this year, and got my hands on some nids. Would appreciate some help to figure out what I should go for next. I have:

1 swarmlord
1 broodlord
7 hormies
2 ripper swarms
34 genestealers
10 gargoyles
3 hive guard
2 exocrines/haruspex (planning on magnets since that what research says)
1 trygon/trygon prime/ mawloc

got some friends who i tricked managed to get into 40k. one went sm, and another went for necrons.
planning on going jormungandr, but open to suggestions.

SL/BL/genestealers are best as kraken. Exocrines and HG best as Kronos. A neurothrope and one more ripper would give you a good Kronos patrol. And 3 more HG.

right now most people would say TYranids best units are:
1-hive guard
2-exocrines
3-zoanthropes (Neurothrope)

If it were me and I wanted to be competetive I'd buy another box of hive guard (so you'd have 6 hive guard because they are so good right now) and I'd buy 2 boxes of Zoanthropes (so you'd have 5 Zoanthropes and 1 Neurothrope HQ). The NeuroThrope is such a good HQ that even if you didn't want to run a unit of 5 Zoanthropes I'd still buy one box so you could just put a Neurothrope in your army. Neurothropes have 2 casts, character and 3++ invul save, just a survivable, reliable psyker HQ that fits in with most builds. That and what you have already would be a pretty decent army you could run against most armies and do well. 

More troops would be good too. Termeguants and WArriors are the favorite choice now of most "competive" players. You need something to hold objectives. Termiguants are lots of bodies that die easy and Warriors are less bodies that are more tanky. Personally I like Hormaguants and genestealers because I think they are cooler. Hormaguants and genestealers are more mobile and tricky. Hormeguants are super fast and get all over the board and can steal objectives. Genestealers are super fast too and hit hard. I personally have more success using genestealers as a counter punch unit after the opponent charges and not always just charging them in head first because they are quite a glass cannon. termiguants and warriors are "easier" as they usually just sit on objectives until they die.  but you do need some type of screening unit (personally I use termiguants) to screen for your HIveGuard. HiveGuard put out a ton of damage but they are useless if they get tagged in combat and can't shoot there weapons.
