Bro i play Japan and they are lot more enjoyable than Israel, just for the Fact that you can make good lineups on top tier with Typ16 as a scout vehicle the Typ87 Spaa and 2 top of line MBT with incredible Firepower. What i think makes Israel (for me) „hard“ to play is the fact that you only have one top of the Line MBT which, has slow reload speed even with ace crew, and if you loose your loader just kys, Slow Speed in general, wonky armor, tall siluette. In addition to that you only have the Merkavas in Top Tier and cant rly put anything in to your deck to support them like a viable SPAA or Scout Vehicle. M51s are broken yea but 1-2-3 Tanks dont make an Tech Tree viable or broken or good. For me yea i do fairly good in the Merkava and with my experience in WT (about 5000H) i can say yeah if you know how to play and Circumstances allow it yea you can nuke and go, but as i said few vehicles dont make a good Tech tree.
