What is the community's thoughts on the changes to cards like hog, knight, pump, bait cards and prince/guards. I can give you my input which I also posted on reddit.
5K+/GC player. To me, there is hardly change to hog. The interactions are basically the same as before. I don't see a difference on ladder or GC in terms of usage rate.. I cannot differentiate between 1.5 and 1.6 hit speed, and the 0.1 delay on the initial hit is very small from a macro perspective. Very few matches are decided on this slight change. Knight is still very strong, so not much change there.
I play bait pretty constantly and I really see no difference in goblin effectiveness except when zap is used on a naked barrel; they do less damage obviously so you just have to be a bit more calculated with placement. To me, Usage rate in GC has dropped significantly probably because people think it's dead from the amount of cards that were nerfed and because rocket took a huge hit. You can no longer just spam troops as before and get away with it.
The rocket, lightning and pump were affected the most by the changes. Fireball, poison, log, zap come in at a close second. Arrows not really affected. Haven't seen too many people using pump on ladder or GC except with 3M, which they are trying to bait your heavy spell so they can split 3M in the back, so that makes sense.
I'm only seeing mortar cycle 1 in 5 matches on ladder compared to 1 in 3 as before. Which is still a massive usage rate on ladder, much like RG when it was OP. Mortar users are probably finding it harder to turtle and toss rockets and other spells. Also more heavy tank cards are being used so that might also contribute to the change.
Prince is noticeably stronger. Not sure about guards... their shield can still be knocked off by log so I'm indifferent as of now, but this could change as the dust is still settling from the balances. Giant/poison/MM/guards is not as OP as before, but it was definitely helped with the buffs and I'm seeing different variations in GC and ladder.
